After NGP Racing rebuilt my engine in 2015, I found out about LiquiMoly. Read up on it and sticking with L.M.
im still on liqui moly 10w60 gt1
I'm a fan of Liqui molly GT1.
Liqui Moly oil is the gold standard that alot of Audi guys use.
I use Mazdas 5w-30 Ultra DPF. Mazda once said that this was the oil that they're using, so I guess what's used by mazda can't be too bad for the rex
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 always used the Liqui Moly Top Tec 4100. Got mine up to 450km so far and still going within my family.
I've used liquid molly for years now, and it's the oil in my 23 GTI right now.
Ughh. How did I miss that! I thought I was just saving $5 a liter for the same thing. I am so annoyed with myself. :banghead: I just pulled up the specs for both and indeed the Synthoil has a viscosity index of 171 vs 180 for the Leichtlauf. Also the NOACK for Synthoil is 12.9% vs 10.0% for Leichtlauf. From what I can tell the 12.9% NOACK of Synthoil is what doesn't allow it to have the VW 502 00 approval.
