Engine oil RED LINE or OEM Audi

With the redline, my car barely burns any oil, and significantly less is directed to my catch can. Night and day difference.

Redline is what I'm currently using for engine oil, shock fluid, and brake fluid.

Redline 5w-40. 6k mile intervals. Probably much nicer than what my little GTI needs, but I like supporting local businesses and it's amazing oil.

I use strictly Redline oils for all my fluids except premix. Engine oil is Redline 10w40.

Redline recommended 10w-40 Full Synthetic for my 1.8 solid lifter JH turbo application and the tech guy suggested modern synthetics don't cause seal leakage (like OG synths of 25 years ago) and holds up way better than the 40w rating in hot temps and protects much better when cold than even the current crop of Castrol 20/50 dino oil I was running. I swapped over the M81 to the same Redline oil and have not yet noticed any new oil leaks yet.

I run the 5w-40 in my 2004 Audi A8 and both of my power strokes just because it's handy and the diesel grade oil is overall better than the other synthetic I was running in a 0w-40 weight.

I use only Redline for all my oils-fluids. For engine oil, I have used 10w40 consistently.

Used to use Motul, now switched to Red Line for the higher zinc content and high heat stability. I rallycross my daily so high RPM and high heat.

Redline 5w 40 since break-in, 254k miles later engine still going strong. Plenty of other repairs done, but no internal engine repairs required.

2012 3.0tfsi turned out to be a mild hybrid as it burns 1l/5k km.
