You are very correct. But my focus now is reading more about the 0W16 to see if I feel comfortable using it in my car in the near future. So, far it is looking good that I will be putting the 0W16 in my car when I decide to change my current oil.0w-08 is old news.
They bench-tested the oils in a Toyota Prius/Prius Prime 2ZR-FXE engine (firing engine) to measure the fuel-economy improvement. They also dyno-tested the oils in a Nissan Rogue Sport MR20DD engine (motoring engine) running in a real vehicle. "SAE 0W-8 high-moly oil demonstrated 0.5% fuel...bobistheoilguy.com
And Honda is all in on the TGDI bandwagon, while Toyota shied away for it except for the Lexus NX200/GS200t/LS500, GR Yaris and the new 2022 Tundra. There’s reason why D1G2 oil, as well as API SP/SN Plus and the newest BMW/Mercedes/VW oil standards cut on on Ca as a detergent additive.Many years ago I posted a similar question, about mixing oils of different brands and/or different types, here on BITOG. One of the old timers pointed out that there is a risk involved, that should be obvious to most of us here, but is easy to overlook.
Each motor oil is designed with it's own add pack, with different companies using different formulations for detergents and antiwear additives. Even within a brand, a HM oil may have a different add pack than an extended life motor oil.
Let's take your formula for an example. Castrol uses a heavy does of calcium and magnesium for detergents, and primarily phosphorus and zinc for antiwear. Toyota uses even a heavier dose of calcium, but also adds a good share of moly. Now that you mix them, the oil in your engine doesn't quite measure up in overall add pack to what either Castrol or Toyota engineered. This garage science experiment isn't going to protect your engine in quite the same way that either company intended.
This may be fine for a single oil change once in a while. But for one oil change after another, to never fully protect your engine, is risky.
You may reach out to Molykule and see if he still feels the same way.
You were right. I put my psi to 36psi and continued my hypermiling and my mpg went up to above 60mpg. Honda recommends we run our mpg at 33psi cold, but I like to run mine at 3 above. So, I run my tires at 36psi.ummm are you sure your not getting lower mpg due to the summer blend of gas being replaced by winter blend? that and tire pressure would have a huge impact on mpg, always....
Lol, so true. I wonder how much oil is left in the car when one completely drains the oil when one is doing an oil change at home. I wonder how much is left before I add the 4 quarts that my car takes.Just a reminder that everytime you change brands and/or grade, you are mixing in probably a 1/2 qt of the old oil with the new. So you be mixin'
