Engine oil RED LINE or Motorex

Using Redline 5w-50 on my E90 M3. it's supposed to have a similar viscosity at high temps as most 60wt oils. Comes up to operating temp faster and doesn't overheat.

I also switched to a 50 weight, Redline.

I was seeing moderate oil consumption and the heavier viscosity seems to have fixed that issue

The best oil to use is the RedLine full synthetic two-stroke Racing oil. Modern full synthetic two stroke oils are way better than older oils and work great.

Red Line products go in all my cars. AMSoil and Motul also quite good.

I use redline hp 5w30 for my n54. 7500 mi intervals. I’m at 113k miles currently. At about 90k I send my oil off to blackstone for an oil analysis. Came back in very good shape and they indicated I could easily go to a 10k mi interval.

I use redline high performance 5w30 and I don’t burn a drop of oil even with 7500 mile intervals on my n54 powered 335is…With bmw synthetic my car would burn about a quart at 7500 miles.

I use Red Line in everything. The M3 gets 15w-50.

Well I decided to try Motorex on my F800 GS, bought the 4T Top Speed full synthetic, in 15W50, boy I cant help it but recommend this oil, the gearbox is so smooth and silky.

With the redline, my car barely burns any oil, and significantly less is directed to my catch can. Night and day difference.

I tried the redline 5w30 previously which has very high levels of moly (>800ppm) and the results were not as good as the moly-less 5w40.
