Quick question for a guy who really doesn't know a whole lot on synthetic oils. I have a 97 2.0L Jetta with 215k on the engine. I've been using 10w30 oil. I'm thinking about switching to synthetic. I don't push the engine hard (no mods to the car) and just would like to know what kind of synthetic I could/should consider for driving in Ontario summer/winter weather.
cheers for your help in advance.
