A reminder to run Top Tier fuel and avoid cheap gas

Ran across this in my feed. I don't see a lot of Mazdas in these videos.

Yup, I make sure to use TT at least every other fill up...

 

[RL911]

Always!

I don’t know about today, but years ago Chevron added more Techron to their premium gasoline vs the 87 octane.

I saw this last night lol I think I am going to be putting mid grade from now on on my 2024 I was told that Shell gas is the best.

Here it is mostly Shell and Philips 66, with a smattering of smaller ones.

The ones that are not on the list are Casey's and Sam's Club.

I had a mechanic tell me that higher octane fuels can burn holes in your pistons, plus a whole other myriad of problems.

They do great work for me, but this line of thinking is absurd. I've been running 91-93 through my vehicles for years with no problems.

Octane is literally just resistance to detonation. How in the world could it burn your pistons, and how would performance cars avoid that?

I think you may have understood that the wrong way round. LOWER octane fuels are subject to detonation (knock) and THAT can burn holes in pistons, etc.

When he was saying it, he was sounding like a mental person explaining a conspiracy theory.

I need a new mechanic.

Yeah, and higher octane has nothing to do with top tier gas...

Over here (Canada), I stick to Shell, and sometimes Co-Op or Costco. I know Domo and 7-11 gas isn't Top Tier certified, so I avoid fueling at those stations when possible. I was surprised to learn that Petro Canada is not Top Tier certified, while Tempo fuel is.

I am also in Canada and I have been using Shell mostly sometimes Esso

There is a great video on youtube about gas quality and consistency and which places to avoid.....basically go to shell, exxon or chevron for quality gas to not carbon foul your s*** in no time flat. There are top tier places that aren't really. That miniscule savings per tank will be blown up by replacing your engine and burning more gas due to worsening internal conditions from crap gas.......carbon build up, injector clogging and also screwing up the cat. Saving 3-4 dollars a tank will quickly vaporize replacing or repairing those. There is also a good video on which fuel treatments are BS and which ones actually work....look for PTE. If no PTE then avoid the snake oil crap that also helps destroy stuff. So yes, a 2 yr old vehicle can be effed up that soon on bad gas and snake oil gas treatments.

The good thing about using Chevron gasoline is that you can buy bottled Techron, which is the same chemical already in the gasoline. That is if you feel the need to add extra fuel detergent.

You need to find a different mechanic, and never go back to that guy again.

I'm not kidding.

Higher octane SLOWS down combustion flame travel time. Thus it reduces engine knock, pre detonation. Engine pre detonation WILL burn a hole is a piston. Depending on how much pre detonation determines how fast.

I've experienced ruining a race motor that was running lean and melted the pistons. Its not a pretty sight. Also had an injector fail and break a piston as well.

On our DD, low performance, engines it will be difficult to hurt them buy running lean or with to much timing with a stock ecu tune. Both produce pre ignition. Hopefully our knock sensors do their job and reduce timing to protect the engine and throw a code. With that said, if one hears detonation, marbles inside the pistons, let off the throttle and pull the spark plugs to confirm.

Aside on knock sensors, they are tuned to a stock engine System. Changing the exhaust Cat Back, changes knock frequency. We use to dial back knock sensor sensitivity and eventually turn the off on street rods. So buyer be eare when modifying exhaust.

Back to race engines, we "READ" our spark plugs, looking for dark specks on the porcelain. Also confirm timing and fuel.at max rpm and load. The specs are piston material from detonation. We have 2 NTK O2 sensors, $350 each and 8 egts sensors. We STILL confirm the ecu log by reading spark plugs. Further we clean our injectors several times a year. So often that I bought an injector flow/cleaning machine.

We have a tuned turbo CX 5 and always run 93 Oct fuel with a fuel additive that absorbs water and stabizes the fuel. We like many others I cring at the added fuel expense of 93 Oct. It's counter intuitive but to spend +30k for the car and then put the cheapest fuel in it...!

Sort of a penny wise, dollar foolish thing..
