What gas do you use in your Type R?

[CTRHONDATA]

Shell 91 or Shell 93 when I'm in the states. Probably a myth but I heard that fueling from the same brand is "good". probably densest matter, especially on a newer car like the Type R but I've kinda stuck with it.

93 is the best for sealevel altitudes
running the flex fuel e40 tune is the next best thing from hondata, i just run e30

I use Chevron 94 octane

Where do you get 94 octane...? I live in Miami (basically under water) and we only have 93 octane here or racing fuel.... (of course E85 etc) but I have never seen 94 octane...

Ethanol for sure improves performance in a turbo vehicle. It cant hurt the car but with 100 percent pure gas you will get better fuel milage.

Chevron stations out in Vancouver are the only ones that have 94 octane.

Maybe it's just a Canadian thing, eh?

My 2010 TL recommended using only fuel from top tier stations, which I knew nothing about originally. Now I'm a homer and only fill up from Shell / Chevron / Mobil / BP and of course use only 93 octane (since in my area most stations only carry 87 / 89 / 93).

In my 2018 ABM R, I only used 91 non-oxygenated gasoline. Car was bone stock. I put 8,000 general-use miles on it, no track...and no problems.

Now, with my 2019 CW R, I have been doing the same for the first 600 miles. Car is bone stock.

Am I wasting my money on non-oxygenated fuel? I have no plans to track...I believe I will get better mileage with the non-oxygenated than with 10% or 15% ethanol added...agree?

I guess I’m really having trouble finding a definitive source that tells me one way or the other which is better to use in my situation, oxygenated or non-oxygenated. I’ve tried searching for which is best in high-performance engines, but I only find reference to mostly small engine, classic cars and marine use.

Is there a definitive treatise on the topic of oxygenated vs. non-oxygenated fuel in modern, non-modified, high-performance street cars?

(BTW, the car is garaged from November to April (or so) and the fuel is treated with Stabil; I also utilize a “smart” battery tender on battery).

Any opinions and thoughts welcome; those that really know, their responses are even more appreciated!!

I can't add anything useful to your question but my question in reading this is, what happened to your first R?

Have plenty of 93 here in eastern PA, but wish I could find a solid e85 station close to home. :-(

5 gallons of E85 and the remainder 93 octane, usually gets me closest to E40 blend.

Arco 91. Now that it's "top tier" is there really any benefit of buying more expensive gas in CA?

 

[martindtjr]

Costco 91 octane.

 

[razi_fk8]

Shell 99 here in the UK, most tracks here also do 102 octane

The European owners’ manual says not to use fuel containing more than 10% ethanol. It also says that continued use of regular fuel can lead to engine damage. So, I dunno...stop being such a dick, Duck.

because euro people dont have ethanol , they also receive a different tune from factory ,

get hondata and use ethanol

Traded for the 2019!

I use 91 to 93, whichever is available. I'm used to it from my Z.
