For all petrol or diesel 4-stroke engines (also Wankel).
Doseage. At least 20% SX-6000 to 80% oil. Add the fresh oil first, then the SX-6000. (If engine and gears are in one oil system, then 25% SX-6000.)
The engine should cool down to below 40°C, before the SX-6000 is added. If this is a problem, then drive home with only the new oil, and add the SX-6000 the next morning (after shaking it well), just before you drive off. (This assumes that you will then be driving non-stop for at least 40 minutes!) For engines using synthetic oil, take the synthetic SX-6000.
