Synthetic

I heard that synthetic can get through seals easier,my temp is 30 in the winter and 110 in the summer, still confused!

wags, in that climate i would use at least a 15w40 oil with the heat. probably a 10w40 in the cold. yeah i guess the oil could leak. but then again, if it leaks it surely is getting to your critical areas much quicker at start up. right?

here is a link: http://www.pennzoilplatinum.com/

click on 20 facts and then #8 cold temperature flow. now i am not favoring any brand. just say to get all the facts that you can.

It can and will. In that climate and a less than pristine N motor I'd probably use a [b:d3f4ec4090]conventional[/b:d3f4ec4090] 15W40 or 20W50. Leaks aside the synthetic is probably overkill and wasted expense on that kind of machine. If the 15W40 doesn't have sufficient hot oil pressure switch up to the 20W50.
