Price was $17.99. Swapped the harley-davidson synthetic oil in my '08 ultra to red line. The engine runs much cooler with this than the hd oil.

Preface

I use this oil in my 2011 flstse2 stage 4. I have too much money invested in my engine to use anything else. Engine runs cool and quiet. Also if you have that clunking noise in the transmission every time you change gears the red line transmission fluid will take care of that. I use the red line primary fluid also. The chain runs quiet and no clutch slippage through the power band to redline. As you can tell i am convinced that red line products are the finest lubricants you can put in your harley. They are a little pricey but worth every dime.

motorcycle oil quart Red Line RED42504 20W-50 Motorcycle Oil - 1 Quart Bottle (Switch to Mobile/Desktop Version)

This is my second oil change on a new motor. This oil seems to have a bit of a thick/sticky consistency to it. I like it though and it seems to be doing great so far in my bike. I've noticed that i am not as hot and don't hear as much lifter noise as when i was using harley conventional oil. I am now full synthetic/red line products in all three areas. 02 rk.

Red Line Red42504 20w-50 Motorcycle Oil - 1 Quart Bottle
Click to see NoticeRed Line Red42504 20w-50 Motorcycle Oil - 1 Quart Bottle (Auto Accessory)"I've been using this oil in my 2005 buell xb12 for over nine years. I started out with the harley branded synthetic oil. Then i learned that harley just rebranded a blended oil from a big-name manufacturer. Not that it was bad oil, just not worth the extra 3 to 4 dollars over mobile one or castrol v-twin oil. The thing about red line is it is a pure synthetic. Does it make a difference for a regular street bike, i can't really say. The bull engine is air cooled and runs really hot, especially here in the south. Getting stuck in summer afternoon traffic on the highway is absolute murder. I also like to run the occasional track day, just for fun. After all these years and at about 50, 000 miles the bike still runs like new. I opened up the engine to add some hotter cams. And i was surprised to see almost no wear on any metal surfaces. I can't say the redline does something that other oils don't. But i can't say that it has done an amazing job in my engine."


Red Line 42804 V-Twin Transmission Oil, 1 Quart, 1 Pack

Improved the noise when shifting over harley oil on my 2012, 103, streetglide. It also seem to cut down on the transmission whine during warm/hot operation. Imo its worth the cost and recommend the shockprooffluid. . Probably overkill but i also changed the primary and engine to redline, cant speak what the results will be, however, i would think any oil made specific to components and conditions would make it happy! . . Almost forgot, the oil change was done late fall so i only got to ride it a couple of times before i winterized it. The engine noise that sounds like lifters etc, seems to have quieted this down, also, that being said it was later in the season and so the engine never got really hot, per-say. Darn, those 103s sure like to talk to you.

Red Line 42804 V-twin Transmission Oil, 1 Quart, 1 Pack (Auto Accessory) FAQ.

So far so good. Just used in a 3 hole change (redline transmission/redline primary oil and castrol power1 v-twin) on a 2017 sgs. Immediately noticed the tranny shifts like butter (within 80 miles), no clunk going into 1st. Looks and smells funky (pink, "frothy" and profound gear oil smell), but it's all good. Why anyone would put 20-50 motor oil in the tranny hole is beyond me, use this instead. -Notice from Z. Linda, Gloucestershire

I've always used mobil 1 for my h-d ultra classic because it was recommended by a h-d dealership mechanic. He recommended using it for all three holes (oil, transmission & primary). I've had no complaints whatsoever with mobil 1. I decided to tackle the latest fluid change myself. I did some research and decided to try the red line brand and i bought their area specific fluids; that is, red line 20w-50 oil, red line v-twin primary case oil & red line v-twin transmission oil. The only area where i noticed an immediate improvement was with the transmission - remarkably smoother and quieter shifts. The primary - nothing good or bad that i noticed. My ultra has always had minor pinging under load uphill during hot weather. I thought it was something with california fuel but i always run high octane and everything is mapped. It wasn't a big deal, just annoying. I noticed that after using red line oil, the pinging (or what i thought was pinging) is completely gone. Maybe it has something to do with dispersing heat or controlling heat. I'm so happy. It costs more than mobil 1 but to me it's worth it. It just seems right to me to use the three area specific oils. I'm sticking with red line.

- E. MooreHave a 2017 low rider s, came loaded with hd syn3. The tranny was noisey and clunky from day one but at about 500 miles the syn3 seemed to give up the ghost in the tranny. Really hard to find nuetral and very loud clunk. Drained that garbage at 700 miles (supposed to be good for 5000 miles) and now all those problems are solved. In will not use anything else in the future.

I experimented lucas synthetic 70-140, mobile 20-50 and mobile 70-140 for 3 holes 2014 road king they work okay but not happy with the result. After using this red line oil i definitely felt the difference the smoothness of my ride. Also bought a red line for primary and love the shifting, i have a rekluse clutch which is working great for transmission and red line oil for primary. As i said in this review i flushed out the lucas and mobile just to try this oil and very satisfied. My next experiment is to flush out lucas 20-50 and replace it with red line 20-50. Will post after change oil.

Red Line 42904 V-Twin Primary Oil, 1 Quart, 1 Pack

I bought this to supplement the supply in my red line oil change kit. You need a little extra primary fluid than provided. Fast shipping.

Red line's v-twin primary case oil is designed specifically for 1984-to-present v-twin american motorcycle engines, including aftermarket engines of similar designs. Similar to red line mtl, this product is for use in the primary chain case with wet-diaphragm spring clutches. Designed to operate over a wide temperature range, v-twin primary case oil improves clutch operation, while reducing wear and temperature. Where most synthetics are too slippery for clutch operation, this friction-balanced product is designed to provide less slip, smoother operation, and more power in modified engines

I use this in my 2013 ultra and love it. I use red line in all three holes and have never been disappointed in its performance. You can also go extended oil change intervals if you choose to do so. I ve used this oil since the 1000 mile service and never looked back, over 60, 000 miles and i change all three every 10, 000 miles. If you run the crap out of it i wouldn t recommend going as long between changes.

- D. AnonymousSeems to be a quieter primary, not that mine is that noisy. The thing i did notice is a lack of issues with my charging system, so i get the feeling this is keeping the stator cooler than hd syn 3. This is the reason i moved to red line in the first place, was after losing a second stator in 2011, on a ride from utah to nyc. "broke down in rochester" sounds more like a song than an event, but we replaced the stator and went with red line. Maybe its coincidence, but haven't had a stator issue on that bike in 5 years, putting a new bottle of red line in each spring.

Works as expected. Added on 9/10/17: checked at 5000miles and oil shows no wear at all! still a translucent, red oil that shows no discoloration or wear from. Being in the primary cover. All my riding buddies are changing to this oil. Added on 8/21/18: have used this oil for over a year, 36, xxx miles, in my '17 road glide. Magnetic drain plug was clean and has been for last 3 changes. Changed every 5000 miles this season, i had 2 - 5000 mile trips plus another 5000 around town. Will always use (and recommend) this oil in my hd motorcycles.

K&N KN-171C Harley Davidson/Buell High Performance Oil Filter

Wow, another excellent product that harley should have done from the factory. Put a little oil on the gasket before tightening (finger tight only), and this filter backs right off when time for an oil change. For best results, do it yourself. Most monkeys at the stealership crank them down too tight and do not oil the gasket first.

K&n powersports oil filters contain a modern synthetic filter media, designed for ultimate flow with less pressure drop, yet engineered for outstanding filtration. K&n powersports 'spin-on' oil filters feature a heavy-duty metal can. Most of these have a 17 mm nut affixed onto the end that allows for easy installation and removal. The 17 mm nut is crossed-drilled so racers can safety wire the filter to their bike.

- A. TheolaHarley davidson/buell high performance oil filter was just what was needed. Good product, great price as it is less than the dealership!

Folks - if you have a harley twincam, you need this oil filter! . . Harley in their infinite wisdom, put the crankshaft position sensor about 3/4 of an inch away from the end of the oil filter, thus preventing the use of any sort of regular oil filter wrench. They have a wrench with a relief cut. That works terribly, and makes a mess. . Behold the k&n with the welded on 11/16 nut (not 1" like the car/truck filters). You just take your socket and back the filter off. No muss, no fuss, and minimal mess. . I'd never $ $ around with the standard (nutless) filter again!

Good stuff.

I have been using redline products for a couple of years now and i wish i had learned about them sooner. Best quality i have ever found in oils and additives. Yes, they are costly compared to conventional oils but the benefits are worth it in my opinion and experience. My bike runs cooler and better with the piece of mind that my engine is being protected to the extreme. I will continue to use redline and enjoy the performance my 1100 straight 4 enjoys from the fluids i feed it.

In my victory xc made engine run very nice. The 6th gear makes much much less noise. On expensive side, but will buy again.

So far this oil has been working great. The motor did quiet down a bit. I ride a '13 harley ultra classic

F. Rhonda, Lewisham says

This oil is the only oil that quited down my top end noise after doing engine work.

I love red line products, works great in my harley davidson motorcycles. Worth a few dollars more than other brands.

I really like this oil for my 2002 flsts

X. Ophelia, South Dakota

I've always used mobil 1 for my h-d ultra classic because it was recommended by a h-d dealership mechanic. He recommended using it for all three holes (oil, transmission & primary). I've had no complaints whatsoever with mobil 1. I decided to tackle the latest fluid change myself. I did some research and decided to try the red line brand and i bought their area specific fluids; that is, red line 20w-50 oil, red line v-twin primary case oil & red line v-twin transmission oil. The only area where i noticed an immediate improvement was with the transmission - remarkably smoother and quieter shifts. The primary - nothing good or bad that i noticed. My ultra has always had minor pinging under load uphill during hot weather. I thought it was something with california fuel but i always run high octane and everything is mapped. It wasn't a big deal, just annoying. I noticed that after using red line oil, the pinging (or what i thought was pinging) is completely gone. Maybe it has something to do with dispersing heat or controlling heat. I'm so happy. It costs more than mobil 1 but to me it's worth it. It just seems right to me to use the three area specific oils. I'm sticking with red line.

G. Alba, Salford says

Bought a harley used this summer and wanted to change all the fluids out just for piece of mind. Air cooled needs a true pao based synthetic and red line is my go to for the last 30 years of high performance vehicles. I have never had a failure mode related to lubrication using their line of products. The bike continues to run great and i know then engine is protected.

H. Aldana, Nottingham

I was referred to red line motorcycle oils by the fellow who set the world land speed record on a harley davidson sportster. One of the big advantages to red line is that it starts out with a base that is at the top end of the multi-viscosity range and adds additives to allow it to pass the viscosity rating for the lower end of the range. In a 20w50 oil, the base oil viscosity is 50w. Most other oils start out with a 20w oil and put in additives that allow it to pass the 50w spec. As the additive package wears, red line remains a 50w oil. Most other oils start to degrade the top viscosity rating as the additive package wears. Red line uses a 100% synthetic base stock. Not everyone does that.

I just serviced my v twin with redline 20-50 motor oil. It seems to work as well as any & supposed to out preform. We will have to wait & see about that. I may update later. . (update) 02/18/2014. After around 900 miles of road time on my bike it does seem to run quieter than before. I would recommend this product to either be equal to or better than any other synthetic oil on the market.

S. Ruby, Sunderland

If you ride a harley, this is probably one of the best oils for that application. My bike, 2012 flhtk, seems to run a little quieter and as a true synthetic i feel more confident that this oil will hold up to the extreme summer texas heat. I use red line synthetic oils for the primary, transmission and engine too. I also put a lot of miles on my bikes and have never had any oil related problem with red line.
