- 2019 Mazda CX-5 Signature (Machine Gray)
I know Mazda says the car can run on either regular or premium octane. I'm not worried about the added HP or MPG. I'm more curious about which octane would help the engine/turbo last longer since I plan on driving this car for a long time. I also buy "top tier" gas and have been using Shells premium VPower since new.
So, out of curiosity, which octane should make the engine last longer?
Would regular octane be less stressful on the engine because the engine doesn't work as hard to produce the extra horsepower?
Would premium be better since it typically has additional additives to keep the engine cleaner? I think the higher the octane the higher compression the fuel needs to ignite, is that added stress?
Does it matter at all? I'll pay premium to help the engine last longer... I also don't want to be a fool if regular is actually better for the engine overall, lol.
Appreciate any insight, opinion or science.
