Amsoil 10w40 synthetic
Never Clutch Slipping Problems and protects the living $%@# out of your motor. Buy from there site and buy cases. Or you can pay big bucks for there oil at the dealers.
Quick question on the amsoil.
Does the XLO version now carry an
OFFICIAL API rating?
I've noticed the deceptive advertising (aka clever wording) on their web site in the past about API certifications.
They go out of their way to mention the official API certification of the FEW oils they sell that actually meet that requirement.
On the rest of their product line they say things like:
<span style='color:red'>....recommended for all domestic and foreign vehicles requiring any of the listed performance specifications:
XLO 10W-40 Synthetic Motor Oil
API SM/CF, SL, SJ ...
ACEA A1/B1
JASO VTW</span>
That's nice that they "recommend it" for those specs but does the oil actually have the official certification for say API SJ?
Can you look at one of your bottles of XLO and tell us what it says?
If your bike or car is under warranty and suffers an internal engine failure (no matter what the cause) what's going to happen when you show the dealer a receipt for an oil that didn't meet their API specs?
