Liqui Moly oil is the gold standard that alot of Audi guys use.
I’ve been using redline in my 2020 fxlrs for the last 3 years. A few guys I know swear by it.
So far redline 20w60 is doing great in the summer heat
My first service after purchasing my Harley, I used SYN3 in all three, since then I’ve religiously used REDLINE kits.
Liqui Moly Leichtlauf High Tech 5w-40 and 450ml of Liqui Moly MoS2 anti friction additive.
5W50 Liqui Moly on an engine with 156k miles on it.
I’ve used Motul, LiquiMoly, Molygen, and Redline 5w40. Oil analysis was best with the Redline, but it’s pricey…although worth the better numbers IMO.
I always used the Liqui Moly Top Tec 4100. Got mine up to 450km so far and still going within my family.
I use Redline 5w-40 because I noticed my engine burns a quart every 2000miles using other brands or thinner grades. With RedLine there is barely any consumption.
Liqui Moly Leichtlauf (the dark blue bottle) 5w40: This is the oil I ran this sumer, and I'm on my second oil change with it. This oil burned about 2 quarts during both intervals, but did not seem to thin out or break down at all.
