I have yet to see a VOA on Amsoil 15W-50.

M-1 15W-50 Goldcap/Silvercap/V-twin/RP/Motul and Redline are all tried and true in racing.

I am sure the Amsoil product is excellent as well as I use other Amsoil products that are excellent.


Lots of great choices these days!

No matter what you choose you really can't go wrong with any of these.

Torco makes excellent products as well.

Great UOA's with Penzoil Platinum. German castrol (labeled made in Germany on bottle; attainable at AutoZone) 0W-30 is a great product for your cars/trucks...as is Chevron Delvac 5W-40...just an fyi.

You have this thread running a long time so I hope you do not mind if I throw some info in. I'll give one renewablelubes.com they also do custom blends and have tested with alot of factory teams here and abroad. I don't think you can get the German castrol at Autozone anymore but when you could it tested way better than the USA Castrol. Everyone on the BTG site bought it up years ago. I have not checked to see if its back. Also BTG is filled with a ton of Amsoil guys and their oil jobbers so it can be real bias at times. When Bob ran it years ago (but sold out about 2 or 4 years ago) it was a great site but most of your great oil minds have left the site. With oil formulations keep changing what you had a year ago most likely is changed hopefully for the better but some for the worse so if your data is not current I would not use it. The EPA has a lot of say so nowadays and the expense of additives have 5 times itself in the last 3 or 4 years. Then again these companies need to make a profit like everyone else so sometimes things have to be cut out of the mix. Also Joe Gibbs Racing has a good oil yes the old football coach, Nascar owner. Redline is a good oil also and is very stable with a load of Moly as a Extreme pressure additive. here are some good conventional oils Valvoline VR1 Racing and Brad Penn Racing still more than enough zinc and phosphorus your standard anti-wear additives but they keep coming down from EPA mandates. Also 07 Dom.SS is right about most oils that are off the shelf is a Group III oil which really is not a syn. oil at all. Only group IV s and Group V s fall into syn. class. Every oil comes out of the ground and the base stocks are refined into groups and then blended with additives that are man made so oil formulations can be called somewhat synthetic. Mobil oil many years ago tried to sue Castrol oil for false adds saying full syn. and lost. so now everyone is claiming the syn. game (FYI)

Just a brief comment...

I pick an oil...one that appears to be good....run it for say 15-20 hrs...do an oil analysis...if it is good in my application I know... if not try a new product.

I have found in testing Mobil-1/Amsoil/Redline and RP.. that they all were great. Never found one to be "bad"...

The biggest mistakes I feel in choosing a synthetic or any oil... is getting the wrong viscosity for the wrong engine/climate; especially if it is cold out and the oil is too thick.

that would be correct any failures in a motor are not the brand of oil being used but how these motors are maintained, lack of maintenance, over revving and dirt - yes dirt, dirty flame arrestor/air cleaner along with detonation. these are the 4 major killers. I totally agree basically oil has done its job along with the right chosen viscosity.

Min spec for a 50 wt oil at 210 is 85 SUS. The Motul just makes this spec with 87.8.

Thanks.

What is the supposed difference again between gold and silver cap M1?
