Gentleman,
i am tired of some kind of discussions in some other Forums and need some knowledge and hard facts.
Most people say "Dont use 0w- oils in high performance engines!" (e.g. my Honda S2000 with 9.000 RPM redline)
Why? They say:
- The VI Improvers shear down quickly, the oil getting thin fast.
- The 5w- and 10W- oils are more robust, they can take more pressure (in the bearings for example).
- The 5w- and 10w oils have a higher HTHS. The 0w HTHS is maybe to low.
- Use of 0w- oils in cars like Porsche, AMG, Nissan GTR is just becasue the oil companys and the manufactures have made a deal.
My point of view:
- If the oil thins out because the VI improvers shears, i just make shorter OCIs.
- 0w protects the engine better "all-around" because it also reduces the cold start wear.
- Oil has been improved over the years, and oils like Mobil 1 0w-40 have shown that they perform extremly well.
- A HTHS above 3.5 should be good enough for almost any application.
- 0w- Oils perform well in cars like Porsche, Nissan GTR, AMG and so on.
I dont like to open a can of worms, but i need some education. Especially the points "HTHS" and "VI Improvers shear down" interesst me.
