VW504/507 is backward compatible with VW502/503/505. Not sure if it is backward compatible with VW506.01 (If someone could give me the VIN with TD5/V10 diesel engine, I could check it out). VW503/506 is specified for all 2007 to 2008 vehicles and some 2005+ vehicles, VW504/507 is specified for...

Originally Posted By: OVERK1LL I still say it is application and power density specific, even on engines with identical clearances. Look at Ford's Modular engines for example. The "Civilian" versions call for 5w20, whilst the Supercharged Ford GT and Shelby GT500 both spec 5w50. They have the...

0W20 with good anti-wear agent just in case you need to go for long trip.

Originally Posted By: kbohip72 I've asked many car guys and mechanics and the best answer I ever got was that the cylinder walls heated up so much that the oil started blowing right past the rings. Hmmm... I wonder what could be the caused. However, I'll give you my thought and see what you...

Thickness (or thiness) of oil is not all that matter with regard to engine oil. other factors you should consider: 1) Anti-wear agent (ZDDP) 2) Detergents against piston deposit 3) Antioxidants against oxidative thickening 4) Dispersants against sludge 5) Dispersants against soot thickening...

Originally Posted By: vxcalais Why are oil manufacturers saying that thicker oil will reduce burning ? It goes against the grain. We have issues in Australia, Holdens burning oil at 10w30. I agree with the comment on it all being engine dependant. I dont think its a general rule. Thank you for...

Check your PM.

Originally Posted By: crinkles well my owners manual says 20w-50 is OK above -7 deg C for my 2az-fe. I am considering 0w-40 or 5w-50 M1 over 15,000km intervals. however, i have read that toyota prefers ISLAC stds and alos because it is a VVTi engine. Take a look at the M1 Product Guide and...

Ilsac GF4 is designed for fuel economy and the oil which meets the specification is normally very thin (i.e. 0w20 max 5W30). If you have to use a ACEA equivalent, I would suggest you to go for ACEA A1/B1 compliance oil which is also designed for fuel economy. Hope this helps.
