Engine oil LIQUI MOLY or Castrol

i use castrol 5w-40 european vehicle. fully built and no issues at almost 30k

I use the Castrol Edge oil. I was doing 7500 mile oil changes and on this last one bumped that up to 10k miles. I sent out the oil for analysis to decide if I want to step up to an even larger interval. The comments left by the tester: 'Your CX5's engine looks good in analysis! Your results look really good by comparison after the 10,000 miles. Metals are all within good wear ranges, with iron even showing below-average steel wear. Nice! Titanium is just an additive in Castrol. Very nice! Go 12k miles next fill.' I will heed their advice and go 12,000 miles on this next one.

I like this oil, I believe it was Castrol Syntec from the factory (says so on the oil cap) but it became slightly hard to find and the Liqui Moly has been great oil so whatever. I changed my oil last year at about 9500mi and it didn't even get dark until about 7k miles.

Castrol German 0w/5w-40

Doesn’t sheer down…

My B9.5 S5 went through a quart about 3000 miles into the last oil change. This oil change that im on now I havent had the light come on and im at about 5000 miles which is when I change oil. I started taking mine to an Indie shop and they use Liqui Moly oil plus they add this little bottle of addative thats supposed to help lubricate the piston rings better.

I run OW-30 Liqui moly that doesn’t burn any oil either.

I switched to liquimoly oil, mine uses a quart roughly every 3k miles but no issues.

I use Liqui Moly 5W-40 which is on the VAG 502 and 505 list.

I used Castrol edge cos that's what my audi used from the factory.

I use Castrol EDGE Fully synthetic oil in my 2013 Mazda 3 skyactiv. It does burn a little but I did not have any issues.
