Engine oil Shell or RAVENOL

Everyone in the Oldsmobile community recommends Rotella

My machinist loves it

I use it in my 66

Ravenol VMP (best oil hands down for diesel).

I used to use Castrol GTX 20W50 oil with Bardahl B2 additive, but after some discussion on the Bob is the oil guy forum, I decided to try a lighter oil: Shell Rotella 15W40 without any additive. It feels a bit easier to start and runs great (but it did ran great before). However, the oil pressure is certainly lower

I have been using the Ravenol VMO 5w30 formula that you can get through Blauparts.com, I have reduced oil consumption in my 2.0 TSI by using this oil.

I've used Shell Helix Ultra 5w-40 and 0w-40 in my AQY. (we have cold winters here) Both seem to work well, no additional lifter noises, normal mileage. Engine sounded good even just before this years oil change.

Shell T6 rottella can be found for $10-12 (us) per gallon after sale and rebate. It is worth stocking lol.

Go find some Shell Rotella T6 at Walmart and use that. 5W-40, and it is rated JASO-MA so it's safe for wet clutch applications. I run it in both bikes and my car; it stands up to sheer and fuel dilution well.

Rotella T6. Don't waste your money on special bike oil. I used it in my ninja 250, my sumo, my speed triple. same oil for everything.

I ran either Mobil 1 or Castrol VW Spec oil in my 08 2.0 TSI and had the usual high burn off with no visible leaks for 1st 100K or so and then switched to Ravenol VMO VW Spec oil I buy on line for a premium price but I like the fact there is little burn off in 5L change intervals which should equate to less carbon buildup in the upper intake of the heads. I have not done an oil analysis which would be helpful to know if I should be waiting to 7,500 or more before I change filter and oil. I had the misfortune of a valve spring breaking at 125K that lead to the head being removed and rebuilt at VW Dealer, the head mechanic was amazed how clean engine was (Mobil 1/Castrol) and the honing lines on the cylinder walls could still be seen indicating very little if any wear. I'm at 156K and burn about 1/2 quart every 5K and engine is as tight as Day 1 with APR Stage 1 Tune

Personally I use Ravenol VMO that I buy online from Blauparts that is made in Germany, IMO the best I have ever run in my turbo 4 cyl VW engines and get almost zero burn off in my 2.0T over 5K miles changes and I am now at 150K.
