Ah, didn't notice he was from Canada. Right you are!! Don't use it.AdRock said:It never gets hot enough in Canada to need an oil that thick. Stick with 5w-30
CanadaStang said:Kinda heavy. Heavy oil robs power. If you are driving your car in very hot weather it would be OK., but this time of year I wouldn't use it.On cold mornings, with 15-50w oil it will take a few moments for it to get up into your motor and causing premature wear to cylinder walls, rings, bearings.
Silvr04GT said:What about between 0w30 and 5w30 which one of those would be better?
COBRA90GT said:After looking at your location, I would use the 0w (because it would have better "flow characteristics" at near freezing temperatures compared to the 5w, and flow even better than the 10w). All three types of oil (0w, 5w, 10w) will, however, flow the same once the oil/engine reaches operating temperature.
The first designator number simply tells you whether or not the oil will flow well when it is cold outside (you want the oil to pump up freely through the engine ASAP, to avoid engine start-up wear). Having an oil like a 0w-xx or 5w-xx oil will get through the engine quicker than one that is 10w-xx.
That's not completely accurate. They did use that for the first few years of the 4.6 but for the last two-three years 5w-20 is what is recommended.jbrown said:5w-30 is what ford calls for, I use the mobil 1 too.
