Engine oil RED LINE or OEM Audi

I’ve done both and extractor takes out like 97% of oil. I still had about a half cup when I pulled the plug.

I stand by Redline 5w20. Not that I have bad “hemi tick” on my 5.7 but I swear the valvetrain is the quietest when I use that oil.

I personally use Red-Line products, and it's the absolute BEST products out there. Their 2 Stroke racing no smoke oil is OUTSTANDING and 2nd to none.

Redline and royal purple filter for my 17 ram sport 5.7. 60kish on it now.

I always used redline 5w50 on my S65 runs very well and redline has a great reputation of quality oil especially for its high performance cars. Takes less time to warm up too in low temperature climates.

I've run Redline in my '01 Golf & my '10 Touareg TDI's for Hundreds of thousands of miles. No worries!

2004 Dodge Ram 1500 5.7 Hemi 255,000 miles Redline 5w30 full synthetic Wix Filter Lubegard Biotech with each oil change....... 5,000 mile intervals. Had a hemi tick when i purchased used in 2007 {off lease} with 32,000 miles on it. The Redline and lubegard have a hefty amount of moly in them which helps keep the insides slick and hemi tick at bay.

I use Redline but it’s about the same price if not moreso.

I have a C7 3.0T A6. I put about 2 quarts of oil in it in between oil changes depending on how hard i drive. I don't have a check engine light. The engine doesn't knock, it runs fine.

Why do Audi’s burn through so much oil? One thing I don’t miss about my 2019 Q7 is the constant adding quarters of oil throughout the year.
