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.
