Mobil1 "burn" easier?

[cbrown9064]

Take a look at this thread. I can smell burning oil on high rpm decel. When autocrossing, no smoke on accel, but lazy blue smoke from tailpipe on decel through a sweeper.

it got me researching that perhaps the use of Mobil 1 is to blame? Some say certain vehicles use oil when they switch to M1 and stop when they switch to something else.

thoughts?

I use mobil 1 (5-30) with no PCV (ran to a breather/separator tank). Definitely smell it, and on decel only like you mentioned. Haven't noticed exhaust smoke but my exhaust ends at the axle so who knows, I could imagine with the PCV it'd end up in the exhaust. Interesting info.

Yeah...I have both valve covers routed to a catch can and end up with a yellowish clear fluid that smells like oil when I drain it.

Not going to get enough miles yet this year to test the theory, but will change to a different oil in the spring and see what happens...

Yeah, I was going to give Amsoil a shot when I got my transmission from them but good lord. Used to 2*.00 for 5 quarts at Walmart for M1, Amsoil was like $12-14 a quart. $90 for oil alone is rough.

Preferred Customers buy Amsoil Signature Series at $8.00 per quart. You can't compare cheap group III hydroccracked petroleum (Mobil 1) to a true group IV PAO - group V Ester blend like Amsoil Signature Series.

Yeah I talked to Bacon and he has a decent deal. Ends up my smell I believe is head gasket related.

Is RP HPS Group III or Group IV PAO? The "regular" RP is group III...to my knowledge anyway?

Great question, the way it was shearing last year on oil analysis....there is no way it was a true synthetic.

mobil is thin, builds heat then burns baby burns
