    Those of you using Redline oil in your 360's, have you stuck to 5W40 or are you using another formulation? I know there has been alot of talk in using lighter weighted oil but I only find it confusing and makes me feel like I should stay with the manufacturers recommendations. Btw, can someone tell me where I can get 5W40 oil in either Redline or Q -Horsepower here in Canada. I've researched around and nobody is willing to sell me 5W40. I guess someone's got a hold on the oil companies?

    First, Redline is the best oil for your 360. I recommend 0w40 because it less wear on cold start. If you can’t find the 0W, 5W is fine. Use the internet to buy it. It is easy for you because you can get it by ground because it is hard by air. Good luck.

    Just found it at Precision Tuning Motorsports in Ontario. A little pricy compared to the US (12.99/bottle) but at least they have 5W40 and are willing to sell it to me. I should have it in 2-5 days. Thanks for the feedback.

    Redline data
    xxW-yy -- cold -- warm --HTHS
    ------------cSt----cSt----cP
    10W-30 -- 70.0 -- 10.7 -- 3.8
    00W-40 -- 81.0 -- 15.1 -- 4.0
    05W-40 -- 94.0 -- 15.1 -- 4.6
    10W-40 -- 93.0 -- 14.6 -- 4.7

    The increase in cold weather startup protection is obviated when the oil gets hotter then 212dF. Thus while 0W-40 is fine for startup protection, it is marginal at track temperatures. 10W-30 is almost as good as 0W-40 at track temperatures, and much better for startup, and perfectly adequate for normal operation.

    10W-40 is thinner at startup, thinner in normal operation, and thicker when it really counts (compared to 5W-40). Thus, 10W-40 is better for your car than 5W-40 under pretty much any conceivable set of circumstances.
