I only use 5w40 motor oil and a Mobil 1 High Endurance Oil Filter and also fully synthetic Mobil 1 gear lube in my 96 A4 Quattro.

Perks of working for

 

I use chevron 5w40 synthetic - 502 spec so its good.

Even with synthetic and OEM filters, I change it every 3 months/3k miles (usually ends up 3 months and 600-1000 miles because I drive my other cars more)

 

Just like some should walk into any VW/Audi service department and see all the Passats and A4's in for engine failure due to sludging up fromrunning non synthetic oil. Full Synthetic wont sludge up and bake onwhen its cooking inside turbo's and and sitting in blazing hot oil pans and other parts of the engine.

 

Pentosin 5W40 synthetic from ECS Tuning.
Changed every 3K miles.

 

Im surprised more people dont use Pentosin. Its very reasonably priced even with ECS's high shipping costs. Good stuff too, I ordered some a few weeks ago and am running it right now. Im usuallya religious Amsoil user though.

 

I hear mixed oppionions about the Pentosin 5W40 synthetic from ECS Tuning. I usually use Amsoil 5w 40

 

What were the mixed oppions that you heard?

 

some swear by it and other say that they have noticed lower oil temps while running mobil 1 or amsoil and cleaner looking oil after they drained

 

just rumors iv'e heard over on the zine but im going to be trying it since a buddy of mine got a hookup with a couple of oil change packages from ECS

 

Hmm.. Id think that there would be too many variables to say for sure one way or the other if any of that is true. Unless there areconclusivetest results or more detailed data about each oils properties etc. Interesting though.
