Topic: What is the best motor oil for my Screamin Eagle 110... motor? (Read 30883 times)

There's nothing wrong with it. It's not the highest rated stuff out there, but it's still one heck of a lot better than HD360 oil (dino), or quite a few other motorcycle oils. I wouldn't use it in the primary and trans, however. Application specific lubricants will work better.

I've always ran Mobil1 V-Twin 20w50 in the motor, their 4T 10w40 in the primary, and the 75w90 gear lube in the trans.
The others folks mentioned above, Amsoil, Redline, etc., is good stuff too, but the Mobil 1 is much easier to find all together at the local autoparts places.

Mobil 1 V-Twin 20w50 (engine), Mobil 1 Synthetic ATF (primary), Redline Shockproof Heavy (transmission)

Whoa, I've never heard about using ATF in our primaries? I dunno about that??

Works great mrmagloo. Think about it for a moment. The main thing the primary lube does is to lubricate two sprockets and a chain, and cool the clutch. What's in an automatic transmission or transfer case that's very similar? Clutches, gears, chains.

ATF is specifically formulated to work well with wet clutches. Of all the various lubes I've tried in my Harley's, ATF has been the best in terms of reducing clutch drag and other clutch issues that are so common.

You have a point - I've just never heard of that before?

amsoil 20/50 in the engine, redline heavy shockproof in tranny, amsoil supershift ATF in primary. if you go ATF make sure its type F.
by the way, i did change the primary chain tensioner at 25k. a little wear but since i was there why not. not a cheap part on the new bikes, 100 bucs

Syn 3 is all I use in the crank and primary and have had no issues in the total of 4 bikes I have used it in.

Motor: Torco straight 50W "60deg. and up"
Tranny: Red Line Heavy Duty Shockproof
Primary: Spectro Heavy Duty Primary Chaincase

Three great performance fluids with three diffrent colors to pin point leaks

I have used both.

I decieded to use Mobil 1 versus Amzoil because you can get Mobil 1 V-Twin at Walmart's, Autozones and a lot of dealers.

Both are very good.

that said, I am going to try Redline Shockproof to help the shifting.

Joelgonia · « **Reply #27 on:** June 30, 2010, 10:28:44 PM »

In shop replacing with Lucas syn now -- different oils for engine, trans & primary. I'll let you know in about 100 miles what I think. Specialty mechanic swears by them - first time for me, so a bit skeptic. Always run HD w/o any issues, but wanted to lower the heat and smooth out the shifting. You guys run Lucas??

Redline in all three holes (20w50 in engine; heavy duty shockproof in tranny; and Redline V-twin Primary case oil in the Primary).

Joelgonia · « **Reply #29 on:** July 01, 2010, 08:44:03 PM »

OK -- temp is down, runs quieter, and I can find First gear!!! I'll put about 500 miles on and report again

I use Amsoil in the motor but want to switch from the HD oil to Redline heavy duty shockproof in the transmission. Any know where I can buy Redline?

Mobile 1 here between oil changes.

I and serveral friends use Amsoil 20-50 motor oil in ALL 3 holes. Works great and they even reported an improvement in shifting. ATF is also good in the primary if that's the way you choose to go.

Cheers, Moe

Amsoil products in every cavity. Motor runs quiet, tranny shifts flawlessly.

Mobil one 20/50 in the engine, 75-140 Mobil synthetic gear oil in the transmission, and mobil synthetic ATF in the primary works great

Synthetics have been proven time-and-again to resist thermal breakdown way longer, to produce better mileage and better power than petroleum (dinosaur-juice). Anything dino-juice can do synthetics can do better longer. I've been using them (Amsoil, Royal Purple, Redline, Mobil 1, and others) wherever I can, whenever I can since 1985. Motorcycles, ATVs, snowmobiles, boats, cars, trucks, motors, tranny's (manual and auto), rear-ends, transfer cases, you name it, can all benefit from switching over to synthetics after initial break-in period. The motor, tranny, rear-end, etc. need to wear-off the high spots and smooth things out just a little bit to break-in. The sheer and heat during break-in is VERY harsh on all the oils. Whenever possible change out all the lubricants at the earliest recommended service interval. H-D recommends 1,000 miles. I'd always done the same with cars, trucks, etc for as long as I can remember. If you can afford it switch to a good synthetic product. Engines with 200,000 miles run like new and show no wear on inspection! Auto trannys really benefit from switch to synthetics.

I switched from factory dino juice to Syn3 all the way around in my '06 Road King Custom (88 cu - 5-spd) at 1,000 miles. Tranny seemed noisy/clunky! I did some research and switched to Redline Syn 20W-50, Redline Syn Primary case oil and Redline Syn shockproof tranny oil. I switched to Redline in my '08 Road King (96ci - 6-spd) at 1,000 miles. Just did the same with my '09 CVO Road Glide at 2,500 miles. I bought it used with 1950 miles. It was serviced at Performance H-D in Syracuse at 1,000 miles for the 1st owner. He had some kind of gear oil in the tranny -- prob 90 weight, or so.

Redline syn tranny oil with shockproof was a major improvement over everything I've used. Redline primary case oil looks and acts very similar (same viscosity, etc.) to the way ATF does. My friends who race use synthetic ATF in chaincases on snowmobiles and motorcycles.

I like Redline products. They are specifically designed to do the best at each function.

I buy them at Hillside Motorcycle in Munnsville, NY. check out their website www.hillsidecycle.com/

I am running the redline in all 3 holes and love it. You can buy a power pak that has all you need directly from red line.
