Engine oil RED LINE or OEM Volkswagen

I use redline high performance 5w30 and I don’t burn a drop of oil even with 7500 mile intervals on my n54 powered 335is…With bmw synthetic my car would burn about a quart at 7500 miles.

I use Red Line in everything. The M3 gets 15w-50.

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.

The oil spec for the 1.8L engine in my 2019 Golf Sportwagen S 4motion is 502.00 (5W40). After my last oil change at the dealer I questioned whether they used the correct oil because the service ticket was written up wrong. The dealer supplied these photos to show how the different grades of oil are actually different colors. The oil on my dipstick was caramel colored, so I knew it was the correct grade for my car after all.

Wife has a 2015 jetta with the 1.8t and burns 1L every 500 -700 miles. My 2016 a3 burns relatively nothing but maybe half a liter every oil change interval and has same engine.

So when i changed the car to 10w40 redline I noticed that the car began to knock around 3-4k which it didn't do before and now it seems to slowly get worse.
