Engine oil RAVENOL or OEM BMW

I have a BMW e36 and it is standard practice to run an extra quart of oil at the track to prevent oil starvation and lifter tick. I have been doing it for years with dozens of track days along with many other people I know with no issues.

I have an Octavia 2.5 vRS TDI and it has 450k km now, it only drank 5w30 and never an issue, not even in cold winters and I had a few -25 starts and it started right away, at the first key turn.

Original BMW 5w30 LL04. I'm sure other brands with the same specifications will be perfectly fine as well though.

I recommend checking your oil level at 3000 miles because some vehicles burn oil. BMW and Audi especially, at 1500~2000miles I will top off.

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

The oil i have run: VW brand, Castrol and Ravenol all 0w-20 that meets 508/509. Basically on cooler outside temperatures the oil does run slightly higher than on hotter days.

Oil consumption is a common problem. My original E92 consumed a quart of oil every 1K miles. My current car does not.
