[FC] Oil additive??

[J R Read_HML]

I don't (often) buy their gas, but I've had Mobil 1 oil in everything I own 
for 30+ years and have not been disappointed.  However, I'm aware of the 
(relatively) recent change you mentioned.  It is causing me to re-look at my 
choices.  Right now, I'm thinking the "diesel use" oil might be the way to 
go (for the Vairs) on the Mobil One.  Any comment?

Later, JR
