i run royal purple 5w 30 XPR its 12 bucks a quart

 

^ Wow, talk about pissing money away. There are plenty of oils that will work equally as well for ~$5/qt

Those oils are ones that paid to get them approved. Other oils meet the same specs but never paid to get that appoved status. But there are people in hot weather citys that run 50w oil also. Also he only said he did that on ones that consumed higher than normal amounts of oil

 

I really don't believe that unless you can prove it true. I doubt any of the oil brands simply pay to have their names put on the list. I would believe that they may submit their oils and pay to have them tested, but not buy their way onto the list. If that ever became known, there would be serious implications and harm to the credibility of VAG.

 

any suggestion on what oil grade beside 0w40 that i should use for my next oil change which is coming up in the next 500 miles

 

5w30 10w40

 

any diffferences between 0w40 and 5w40?

 

 

More companies make 5w40.

 

the approval list is bs. A while back when we first started to distribute redline fluids I got a informational packet the said to raise the weight of the oil if using a synthetic. Synthetics are naturally thinner than coventional. also the 10w60 I use is from lubro moly. Same company as liqui moly. When synthetics started to become popular I remember alot of the older 8v engines used to trigger the oil lights because the synthetic couldnt make the pressure. So instead of running 5w30 we went to 10w40 and the cars tan perfect. Also you want to always have high oil pressure throughout the engine, this has been a fact for a really long time.

 

That's fine, but I think 5w-40 or 0w-40 is plenty viscous for a newer engine. Also, if I have turbo failure due to lack of oil lubrication, I want to make sure I have the recommended type in. The idea is to have the best friction protection at the highest flow rate and to ensure that the oil gets to the tightest areas. 40W is going to flow more easily at higher temps than 60W. If you are able to use (or need to use) 60W, it's because the engine is worn more. I would not use a 60W (or even a 50W) in a newer engine.
