I have heard that non-synthetic (dino) oil has been hard to find in parts of the country, and when it is available, it's more expensive than synthetic. Around here that isn't the case, fortunately, sounds like dino oil is available in PEI with no problem, then Noel? I run synthetic in the '06 Denali. My wife's '21 Equinox is still under warranty so it will stay synthetic long as we have it too. Just an example of a synthetic oil advantage was, back around 1996 we decided to switch oils in the engine of our dirt track race car. Went from Kendall 20-50 to Amsoil 20-50. Next night out the engine ran 20 degrees cooler! We stayed with synthetic from then on. Now in a couple of street vehicles we had, didn't get good results switching to Amsoil. Worst was the 1995 Camry we had. It started leaking oil and would lose oil pressure at certain RPMs after around 1000 miles on an oil change. Dino oil went back in that! Wife also had a 2008 Chrysler mini van for awhile. I was sick for a good amount of time while we had it. Had my brother in law change oil and he put Amsoil in it. Started using a quart every 1000 miles. Traded it off while I was still recovering.
Even though I use dino oil in the tractors and old trucks, I'm not against it at all. Just keep using the type of oil that has been in them as I don't know what switching may do, besides the deal with the Camry and Chrysler. I forget what they called the mini vans.
Sure can't see a reason why the 5-20 synthetic would hurt anything, so keep us posted on how it works, Kenny!
