I love when you see motorcycles for sale with 10k or less miles on them touting their use of synthetic oils, always makes me laugh.

Pick a brand of 20w50 and ride it until you're sick of it-

Been riding my '93 since, '93. I switched to Syn3 when it came out. No problems even against the advice of the naysayers: "it will leak blah blah blah gaskets, blah." Last year I'm still getting 50+ MPG on this XLH.

I wish I could see a thread that started with which oil has caused a engine or any mechanical failures. I would like to see evidence that a oil is bad. Anyone have pictures of a component that failed because of oil. In 40 years of driving vehicles I have never had a engine part fail because of the oil I was using. I always changed my oil at 3,000 mile intervals. With the new synthetics I change all equipment at 5,000 mile intervals.

In my Goldwing I use Amsoil, in my truck I use Schaffers (sp). I will probably run Schaffers 20-50 racing oil in the HD. Oh and I use Mobile 1 in other vehicles. Whenever it goes on sale at Costco I buy a bunch.

Can anyone show a component failure caused by the use of a specific oil?

wrong

Actually, according to a very good source, linsm13 is not really wrong.
Amsoil buys their base stock from Mobil then adds their own additives.
Mobile "base stock", is NOT Mobile 1 Syn. (It's only a base stock). He he!


BTW: Mobile 1 syn is easy to get and as good as any of the best oils.
I ran Redline 20/50 for years, and switched to Mobile 1 Vtwin simply because I can run out and buy it on a Sunday a few miles from home.
Both are outstanding oils.

I don't use Amsoil because of the disclaimer they have on their website that warns you that it's "not recommended for modified motors".
This tells me they don't trust it's durability. So why should I trust it?

**** poor argument.

Bearings fail all the time. Cam journals, bushings, cylinder wear,.... hell, there are endless threads of people having failures!
Do you really think lubrication didn't have anything to do with any of them????

Since when do mechanics send weekly reports to Washington documenting causes of failures?

Perhaps you could provide a link where on the Amsoil site it says "not recommended for modified motors" this is the only reference to modified motors I could find.......

MODIFICATIONS:
Where the engine or operating conditions have been modifi
ed from the original manufacturer’s design, the recommended
AMSOIL service intervals cannot be utilized. An
exception is Dealer-installed, street-legal EFI Stage kits
offered by Harley-Davidson. In all other cases of modifi cations,
oil change intervals are at the owner’s discretion or
based on specific oil analysis program recommendations.
To set up a program, call Oil Analyzers (OAI) at 715-395-
0222 or 1-800-956-5695.

It's been a while since I saw it, but you are correct.
It's not that they don't recommend it in modified motors, it's that they don't recommend extended intervals in modded motors.

Same loss of confidence in the oil, as far as I am concerned.
Might as well use dino oil if you can't use extended change intervals.
It kills the price advantage if you have to buy oil and filters more often.


Modifications and Alterations -
Engines operating under modified conditions (non-stock) are excluded from extended

drain recommendations. Examples include the use of performance computer chips, non-OEM approved exhaust, fuel or air induction systems and the use of fuels other than those recommended for normal operation by the manufacturer.





They must not have confidence that their viscosity will hold up.

obviously they can't make recomendations based on what someone "might" do to their engine. Mobil basically says the same thing.... "Typical Properties are typical of those obtained with normal production tolerance and do not constitute a specification."

ASE Certified Auto Tech for 25 years.
+1 on getting oils changed on time ( most important, more than what type you use)
+1 on why pay the high price
+1 on the oil did not cause the problem
Ok , I'll agree synthetic is designed to take the heat better and will run cooler so +1
History: Been a Amsoil believer sence the 70's when I saw their presentation and results of use in a dirt late model race car. I believed it to be the best oil you could buy.
2007 and I am using it in my 07 Ultra, going on vacation to NC for a long ride and at 80mph on the freeway my engine blew up. The dealer (bumpis in memphis) said that i had one of a few that he has seen ( all with amsoil in it ) that the engine hydroliced. I asked for the oil so I could send it to amsoil and get it analized, they forgot to get me may sample and also they forgot to get me the "exact crank runout reeding" and finally they could not tell me why it happned. After the engine was rebuilt they put in HD dino oil, I ran the crap out of it , almost trying to blow it up again. SO here is my advise on oil for a Harley now.Use HD oil, if you want better heat resistance, use HD syn. For one HD engineers have designed their additive package to be compatible with the metals in a HD so you can't go wrong there. And secondly, the higher costing Amsoil made no difference in my 07 ( I don't believe it was any way a cause like the bumpis svc mgr did) but it's just a great oil- so what - I believe it my be too good now ( that is another discussion) I still use it in my 55 chevy- and change the oil about every 2 years or so.
Oh, and to each his own, in 07 I was chasing cooler running and trans noise concerns that was why the switch. 2010 Limited and I'm still running HD dino and change it at each 5k on the dot, thought I overheated the oil in Branson MO. last summer and had the oil checked and it was sill in great shape.

I have used all the above oils mentioned, I was very reluctant to use the Redline brand due to availability and cost. I gave it a shot and am glad I did, took away alot of ticks and taps in the valvetrain. And also noticed cooler oil temps. I am sold on this oil after all the changes and experiments I have tried this oil is the best for what I am using it for.
