IMHO, that 5W at 35F is gonna be a bit thicker than 10W at 50F. I'd probably put a milkhouse heater under the engine and a wind block under the car and let things get as warm as I could. iMHO, it is just a matter of getting good oil flow right away.
And if you have the stock valve springs, the issues tend to go way down anyway.
Good idea. Thanks much! yeah my friend said the main reason that it could be bad was because it had a higher chance of running lean but i don't think the more dense cold air would effect it that much would it?
