Thread: Pennzoil Platinum European Formula 5W30 mystery - Bob Is The Oil Guy

Thanx for responses.... I flushed the coolant (because of the oil cooler issue) and I am going to use M1 0W40 (Had big dillema between M1 0W40 and 5W40 Euro but after more research I think M1 is a better solution)

Not sure how well it cleans, but there is quite a following for the German Castrol European Formula 0W-30 oil. In fact, there is an entire FAQ devoted just to that oil. http://www.bobistheoilguy.com/forums/ubbthreads.php?ubb=showflat&Number=718643

I have used M1 0W-40 for several years (Volvo 740 Turbo, 940 Turbo, two Saab 9-3 Turbos, and VW 2.0) and my experience is that it does excellent cleaning. My suspicion is this is due to esters contained in the oil that most of the other M1 forumations do hot have or have to a lesser degree.

I have it in my BMW right now with two full bottles of RX for a 6,200 mile (10,000 kms) clean. Its not PP Euro, check the MSDS, it does not use the Slack wax base, and is only SL rated. All new Shell is SM rated...

Slack wax good? Slack wax bad? What do you say?

I've seen the 5W-40 version occassionally. Never the 5W-30 version. Silly that PZ doesn't make it more availiable - same with the 0W-20 PP.

This company sells a full syn. VW 502 approved oil for $5.28 a qt. delivered http://stores.ebay.com/matrixlubricants

Never heard of them before. Wonder who blends their product for them. I see the ebay site links to their web page.

How about using Rotella 5w-40 syn? That will contain more detergents and zddp than PP not to mention the better base stock.
