Uh, oh, the old dino v. sythetic dust up. Let's post the steps:
1. Some debate about synthetic vs. dino oil with some folks voicing opinions.
2. Steve posts about how most synthetics are not really synthetic and how those of us buying synthetic oils are being scammed.
Most "synthetic" oils sold (Mobil 1, etc.) have much lower pour points than conventional oils, and in Canada, do provide extra engine protection in cold start situations.
More important than the oil itself however, is changing it at reasonable intervals. We use synthetic in all our internal combustion engines with excellent results. I use 8000km change intervals in both cars, and the oil is in good condition when it comes out. Probably could go longer, but a few extra changes in the life of the car is cheap insurance...
