What are the benefits of using 20w50 motor oil?
- On engines intended to use 10W40 when on a hot climate, (mild to high ambient temperature on startup):
- Might help worn engines mitigate their oil consumption, as long as mainly driven on the low to mid RPM range (Ideally 10w/15w -50).
- Only usable on warmer (never cold or freezing) climates, OR...
Just One to two cold starts a day, whichever comes first! - Very affordable Oil, no more need to postpone oil changes, if you DIY!
- In a pinch, you can use it to top up your gear-box (or differential, on the thin side), but with no ‘synchros’ eating EP additives either!
- You can use it to top up your Manual Transmission (gearbox), especially if you use a polar gearbox additive alongside.
- HTHS -Bellow, you can see why the best engine protection on the HOT /Hard driving /Racing /Towing /Warm climates starts at 10w~15w!.. 5w-40 hasn’t the high temp(150ºC) high shear resistanceof a 15W-40 (3.7cP), despite having the same Operating Temp. weight (-40)!
