Just a little info on the 20 weight oils we offer..there are 3 of them.
OE 5/20
XL 5/20
Full syn 0/20
The full syn is your "lab" made syn oil. Highest quality base stocks and beefy additive package. If you want the best one, this is it. It has a 25k/15k change interval(25-normal, 15-severe). Of course it runs more, about $2 more per qt than the XL and about 3.50 more than the OE.
The XL is a 6 month/10k mile oil.
The OE is a OEM chaing interval oil, so if you manual says 5k, then it's 5k. This is just a "tamed" down version of the XL. Little lighter on the additives. These two are made from group 3 basestocks, similar to valvoline, castrol and others. Group 3's are highly refined dino oils...still come from the ground. They still offer many of the advantages of a full syn but at a lower price.
The XL and OE were designed to get AMSOIL into the quicklube market. These are more competitively priced with other quicklube synthetics used. Plus no one who makes a living changing oil want to put something in that lasts 25k
So that's the simple breakdown. Some may question the use of a 0/20 if 5/20 is required. It's perfectly fine. The bottom number is the one you need to follow. AMSOIL chose to go with a 0/20 instead of a 5/20 on the full syn probably because OEMs will probably head down that path??
I should probably not limit this to the 20 weight oils...
We also have:
OE 5/30 and 10/30
XL 5/30, 10/30 and 10/40
Full syn 0/30, 5/30, 10/30, 10/40 and 20/50
There are many other full syn oils...diesel, european, powersports, etc. but I'll stop here. You can view them all on my site.
So when you are looking at a certain weight of oil, let me know full, OE, or XL to get you the right pricing. If not, I'll be asking
