"Oil type Typically used in....
5W-30 Cooler climates, like Sweden
10W-40 Temperate climates, like England
15W-50 Hot climates, like Italy, Spain, Egypt"
Got it from a website talking about SJ being the current top grade. Must be very old.
Have you ever redlined that motor for an hour?quote:
By this chart my VG30DE engine should be toast.
I'd say it really depends on the year and make of the engine. Most newer BMWs spec Group III 5W-30 year round. A friend's '01 Audi A4 calls for 0W-30, 5W-30, or 5W-40 year round.quote:

I was going to say that this chart is actually a bit conservative. My BMW stops a 5-30 at 5C (and not 15C).
I used to think the same way. But, I now agree with the charts too. Although there is some variation with synthetics, the viscosity illustrated holds true if you want a long-lasting and clean engine. I've said this before...for all you 5-30 users....there's always auto-rx later on....to clean up the garbage left by the "fuel-economy" oil.
Column A shows "Leichtlauföl" - oil that contains friction modifiers and that also meets VW500.00 (replaced by VW502.00). Those oils are to my best knowledge all synthetic oils and almost always "energy conserving."quote:
Could it be that "A" is synthetic and "B" is dino?
