Post on USMB Subaru forum as above saying use anything bar 'Pennzoil with their wax based oil'. What is his basis for this which I find kinda strange?
as someone said....'parrafin' is a name that used to be given to wax. PA crude was high in 'nitro-parafinnic' molecules which is not the same thing, but it is close enuf that it sounds scary and uses scary language (to paraphrase George Carlin)quote:

Well you know that varnish keeps the non bearing surfaces from rusting don't you.quote:

I saw the insides of my Dad's 4.3L Blazer which has run on Pennz, mostly 5w-30, and there was no sludge, just a very very light coating of varnish on non-bearing surfaces. Looked fairly clean for over 100K.
Well **** , all those peeps out there with spotless engines running synthetic and no varnish must be pissed nowquote:

I had to replace the head gasket on my truck a few years ago. It had over 20 years and 100K of mostly short trips including moderate winters. For the last 10 years, it was getting fresh Pennzoil 5W-30 dino every 3 months. For a few years in the 80's I was using QS and 6 months intervals until my Pontiac Phoenix sludged up (100K?). I had started it on Pennzoil, but switched.quote:

Ive run synthetic in vehicles for 100K's of miles and see the same amount of 'varnish' in there as non synthetic. Of course I actually take motors apart (all engines require an eventual rebuild, regardless of oil used) and Im willing to bet large sums of $$ that the 'amsoil crowd' who claim spotless motors have never actually looked inside any farther than the inside of the oil cap...quote:
