Owner reviews for engine oil

OK, then what works for me is Castrol Syntec 0w30 European Car Formula.

i drive a 95 jetta vr6 i currently running mobil 1 10w-40 but i been hearing alot of good things about this new castrol edge thinking about switching to the 5w-40....im hoping i feel a difference

4 qts Redline 5w40, 1 qt Redline w40 Race Redline blows away the competition... Lumps of ZDDP and Moly with the Race oil mix, fuel dilution pretty much disappeared, and viscosity/flashpoint are well within reason.

i run 20/50 Castrol year round. it actually reduced the burning and smoking of oil on start up, unlike Mobil 1. i'm glad i switched over.

I would stick with a tested oil like Red Line 5w-40 or GC, but that's me.

Sticking with a single weight is a better idea than mixology IMO..

it was 5/40w fully systhic carlube ive been adivsed to run 10/30w genetic oil? i will also use a mk3 oilfilter huseing with the sensors because then i can wire the oil temp up as well which i can keep an eye on

ive been to a company regards this problem , with crank bearing failure , ive had the oil pump , bores, pistons ,rings,, oil ways checked etc were fitted correctly...all they recomend is fit a external oil cooler to help keep the engine oil cool

And I use a 15W40 diesel oil year round here in the Bay Area, currently Rotella-T, but have used Mobil Delvac 1300, Delo and others.

I use Mobil 1 Turbo Diesel Truck 5w-40. A 5w-40 full synthetic is going to work brilliantly in your climate.
