Mits_jc 5th Gear August 30, 2009 Share August 30, 2009 Oil for 4 stroke bike (4T) can mix, but not so sure if the oil is for a 2T bike. Link to post Share on other sites More sharing options...
Ultramega 1st Gear August 30, 2009 Share August 30, 2009 I have some leftover engine oil, maxima 5W40, from my bike and is thinking of pouring it into the car. Technically it should be ok, the car is mobil 5W50. Anyone try before? In my opinion, technically it is NOT ok. My layman understanding is as follows: Car engine needs "slippery-ness", but gears/transmission don't need so much slippery-ness (else you get clutch slipage). That's why in cars you have different oils for different parts of the car. But in bikes, it's one oil for everything - gears, clutch, engine, whatever.... so they make bike oil half silppery half not slippery, slippery enough for engine and yet can prevent cluch slipage (with the help of frictional addictives). If you use this kind of oil as car engine oil, the addictives that gives frictional properties to the oil to prevent clutch slipage will not do your engine any good (remember that engine needs "slippery-ness"). As to whether it will do any harm, i do not know for sure. Link to post Share on other sites More sharing options...

Technically it should be ok, the car is mobil 5W50. Anyone try before? No problem with using 4T bike oil(must be dual spec with API SL at least) for automotive unless you car is consuming engine oil (might damage the CAT due to higher Phos and Zinc anti-wear in bike oil). In fact, if you had modify the engine and de-cat your exhaust, then 4T would be ideal as some sort of cheapo race oil. Good for 10k oil change also.

Trex101 3rd Gear August 30, 2009 Share August 30, 2009 bike to car = ok car to bike = not ok.. the clutch plates will slip For Car to Bike oil, choose those dual Diesel spec oil as Diesel oil and more robust without much anti-friction additives. Safe for wet clutch usage. Link to post Share on other sites More sharing options...

Not all car oil are suitable, only those with diesel spec CI-4 or CI-4+ would be suitable for wet clutch system. ↡ Advertisement Link to post Share on other sites More sharing options...
