Any drawbacks from using this oil in a twin cam gas engine? I like it, the engine is quieter, the oil stays clean longer and the motor looks cleaner too. Will it kill my new catalyst because of its ash content?
You might be better off with Rotella T (synthetic- Its on sale at Wallyworld for 12-13 bucks) for the Wintertime in Pa. I think its SL rated so you should be ok. Delvac 1 is a better choice but its higher doller and hard to find.
