Engine oil LIQUI MOLY or Shell
I use one oil - shell rotella. It goes in my XRL my 4.0 Jeep and my 7.3IDI diesel ????
I always used gn4 but switched to rotella t6 15w40 cheaper, full synthetic. it can handle the heat alittle better and I like the shift quality over gn4. Walmart has it for cheap
I have a 14 Passat. I do full synthetic LiquiMoly with the VW spec. I change it out every 6-6500 miles.
Liquimoly leichtlauf 5w40. Been told it’s a bit better than 5w30 in a 20+ year old engine due to being a bit thicker. Also does better at higher temps and I drive like a dick
Liqui Moly leichtlauf hightech 5w40. Because it matches the BMW LL-01 specification and was formulated to help with the sticky piston rings issue common to many german engines. Noticed lower oil temp under load and a gradual reduction of oil consumption
Shell Rotella (Rimula) 10W40, mines on 165k, 6 months ago I did the O2 Pilot mod and started to use the above oil as it's fully synthetic and made for Buses, Heavy Trucks etc, and so has extremely good cleaning abilities. My oil consumption has dropped almost 4 fold and the cams, rockers, oil filter housing have all been cleaned of the varnish type coating they had too.
I run LM 5w-40 as recommended by my tuner.
The oil type is likely fine, but the viscosity isn't. Ignore what the book says, get the 5W30 out of there. The PDs love to eat cams, and running 5W30 makes the problem worse. Me personally, I run Shell Rotella T6 5W40.
dude stick to the engine oil grade mentioned in the user manual and fill shell synthetic of that grade
US manual states 507 can be used, but you might get worse fuel economy... Mine is about 0.3 mpg lower on liquimoly toptec 4200 5w-3p
