Anyone knows if it's dangerous to swicth to syntec oil (Monbil1) if the car is running on normal oil since i bought it?

I saw Horsepower TV one day, and they used synthetic everything, and I think they acutally gained like 3 hp on the dyno, and some torque. I dont know why you shouldnt...anyone else?

A very good tech at my shop swears by synthetic oil for winter use. He switches to sythetic every fall and back to organic every spring. He has gotten lots of miles out of his engines(last one had over 300,000 on it with out and work being done to it). I switched at about 15-20K with no problems. I say, go for it

What harm comes from switching too often or using a synthetic blend oil. I had gotten one synthetic oil change butnin the last year I've had a synthetic blend oil changes. Any harm done, any benefit gained? Shed some light. thanks

No harm will come to your engine. But do change your oil every recommended intervals. I didn't feel any increase of power when I change mine many moons ago but it did increase my mileage per gallon about 1 mile in city driving and 2 miles on highway driving.

If your car isn't too high on miles (100K +) go ahead and switch. start with the 10w-30 and see if you have any leaking if not you can drop to 5w-30 if you like.

I run 5w30 in the summer and 0w30 in the winter

I have mobile 1 syn. is this stuff ok to use in a hot climate (FL)? I ended up wih leeking for a while until I got it fixed.

Go ahead and switch. It will be no problem no matter what the miles.
