Engine oil RAVENOL or OEM Subaru

Even Ravenol, which is pretty expensive since it is made in Germany from Group V base stock. Great stuff.

I used to have castrol but since i chiptuned my octavia i switched to ravenol and the oil temps went down a good bit and it doesnt use any oil but that could also be because the old oil was 0w20 and the new one is 5w40

Last month I replaced the valve stem seals and it helped massively with the smoke. It doesn't really smoke much anymore, there's definitely still small puffs when taking off quickly, but nothing that I can see in the mirror.

I go with 10w40 Ravenol TSi

My '15 Forester will burn a quart of oil every 1000 miles if I run 0w20.

I switched to 5w30 and it's all good for 5000 miles

I use Ravenol which is 100% PAO base stock.

Well, some manufacturers do have way shorter oil change intervals than Euro manufacturers. The Subaru severe driving interval is 3000miles/6 months, and I do lots of short trips in a desert climate so I usually try to be around 3-4000 to stay on the safe side for warranty and whatnot.

In Germany we driver Ravenol RCS 5w-40 and Archoil 9100....sick combination. i drive it in my c63s and gle63s and volvo S60....

Having had multiple Subarus that leak oil like crazy (they all do when they get old) the leaks are most likely too much for the stop leak additive to fix anyway.

after 2000km of running on it, i see there is quite a drop (30% from the max point). i think that is very weird...
