Engine oil Total or Pentosin

I used to use mobil1 5w30 for 2 or 3 oil changes then switch to Total 5w40 full syn and it burns way less. I think I burn a whole quart every 3 or 4k using 5w30 but with Total 5w40 I burnt probably hald that.

Pentosin High Performance is the right one to use. 5w-40 Pento High Performance 5W-40 is an especially formulated fuel economy engine oil. It is based on synthetic base oils only, the most modern and best engine oil additives currently available and a very shear stable VI - Improver. The combination of these exquisite components guarantees an excellent engine performance under the most severe driving conditions. Pento High Performance 5W-40 is ideally suited as an all season engine oil. Pento High Performance 5W-40 contains a special combination of very efficient fric-tion modifiers which cause the engine to run very smoothly. Even more important, it causes fuel savings in a recognizable way.

I would stick with oils like PENTOSIN/LUBRO-MOLY/CASTROL GERMAN/MOTUL/ This one is easy. Anything not made in the US and is 100% synthetic. I use Pentosin high performance 5w-40, 502/501/500 approved oil.

pentosin/pentosynth 5W40 here, changed it 1K miles ago (second run on this oil), great stuff ecstuning.com sell it for ~28 bucks for 5 liter. I like it much, much more over the castrol from dealership (used that too and after 2K miles changed back to pentsynth). I'm very happy with it.
