Hi Scotty I have a question to ask you please I have GMC Sierra 1500 Denali 2017 with engine 6.2 l my question is if use octane booster that add 4 extra octane and I’m already using 93 octane gas will damage the engine?
It won't damage anything but it will be a complete waste of money.
That engine runs on regular gas. Everything else is a waste of money.
Use the octane the make recommends.
The only reason I would use a higher octane or octane booster is if my engine was knocking.
It would just be a waste of money. Much like putting Premium fuel in a car/truck that does not require it.
Is there a reason that you feel you need an extra 4 octane?
He feels the need, the need for speed! Sorry, couldn’t resist!

It does not hurt your engine, it hurts your pocket.
My advice is to use what is recommended by the manufacturer (GM). The engineers designed the engine with a specific fuel grade in mind, and it simply makes sense to use the fuel grade they recommend.
