Reply to comment by GargantuanWitch in Getgo gas no longer listed on the Top Tier website. Did they drop their certification? by Confident_End_3848

Like I said, today's direct injected engines have issues with carbon buildup that didn't exist with old port injection systems. They are much more sensitive to fuel quality.

Some engines even require dismantling the intake and cleaning it out periodically. Ford and Toyota use direct and port injection together as a workaround. Don't take my word for it, it's an extremely well-known issue that anyone can research.

Are those 1000% perfect sources with no possible conflicts of interest? Of course not, but it's certainly a better data point than someone posting their opinion on Reddit. I'll stick with the recommendation in my owner's manual, especially when we're talking about less than 50 cents a tank.

What kind of car do you drive that recommends it, is it higher-end?

I totally get it for people who buy high-end cars and have to put in like 93 octane. At that point though I consider it a niche/enthusiast kind of thing though. Like a coworker drives something like that, and he's a gear head customizing stuff under the hood that is way over my head. Nothing wrong with that.

But if I bought a new Camry and I had to put "special" fuel in it, that would be a deal breaker for me.

No, just a Civic, but it does have a turbo GDI engine. The manual discusses it on page 541.

Incidentally, Toyota recommends it as well. From page 590 of the 2023 Camry manual:

> Toyota strongly recommends the use of Top Tier Detergent Gasoline. For more information on Top Tier Detergent Gasoline and a list of marketers, please go to the official website www.toptiergas.com

The price difference is something like 3 cents a gallon, nowhere near the expense of 93. And it's not like the engine will explode if you fill up with non-TT gas, it's just advisable over the long run.
