Full synthetic, none of them will last less than 5000 km.
And for RK R20A engine, it only take 3.8L engine oil. You can tell how narrow are the pipes inside.....if you use w40, the oil is hard move inside which is no good for the engine.......
In fact, the main driving range of our engine is 2000-3000rpm, you can't compare it with Type-R which need to push up to 6000rpm-8000rpm (which needs w40 for better protection) |
