If you run the same oil event after event without changing, as the oil gets older it will run hotter with the viscosity break down and carbon build up. Syntethic will do this slower. Fresh oil change first event, close to the same. No change for 3 events, the synthetic will be a bit cooler.
Some say yes some say no. Is syns are better for heat dissipation? Is thicker syns like 10w30 vs 5w20 will run cooler? Is thicker dino would do .
It's a myth. Synthetic can stand higher temperatures before it breaks down compared with conventional oil. That is not the same as "it makes the engine run cooler". I run synthetic because it can withstand more extreme situations.
Synthetic oil vs. conventional oil. Most readers know that synthetic motor oils typically perform better than conventional motor oils in providing protection for your vehicle, but they might not know why.. Synthetic oil is not only refined but also distilled, purified and broken down into its basic molecules.
Now that oil changes will be very infrequent (2K miles) will probably still. Guessing it's running cooler because it's not as hot outside (?) Or are .
I have always used synthetic oil in my cars including a 350Z,. I am running much cooler now since switching from dino oil to synthetic.
Info about synthetic vs regular motor oil, and types of motor oil, automotive tips. oil cooler (similar to a radiator's design) and optimal oil viscosity, you can do away with. . It will allow you to run oil that offers excellent lubrication and high flow .
