Increasing Gasoline Octane Overseas

smittyg37

I have recently moved to Turkey due to my job and have discovered the gas on base in only 90 octane. I have been researching ways to increase the octane and have come up with two choices either mix the 90 octane from on base with the 93 octane off base or use octane boosters to increase it. The issue is gas off base is extremely expensive roughly $9 dollars a gallon. Thats my sticking point. So which option would you suggest? And if it is a octane booster which one would you suggest? I do have a Uprev tune from
Z1 for both 93 and 91 octane. Thank you for your help/ advice.

Retune for the octane you have access to. Octane booster doesn't do anything. It would take gallons of the stuff to make any difference. Unless you have access to toluene there, you're not going to be able to boost the octane any appreciable amount.

torco accelerator works but you would need a quart or more per tank at $21 a quart plus shipping. cheapest route is almost always toluene or xylene if you can get a source for it.

Toluene is a bit better. If you run Xylene you need to run something like Marvel Mystery Oil as well.


How much is gas on base?
Also, is your octane getting rated the same as it does here in the states because almost no where else does it the same. (Here it's AKI, which is [RON+MON]/2, I believe most other countries use RON OR MON)

First of all thank you all for the the advice and direction. I have been searching all over trying to find a alternative way to get into the right octane range. The gas on base is not to bad roughly $4 dollars a gallon since they use liters over here. On base the rating is 95 FRG which I tried to research and had difficulty finding anything in that unit. Off base the gas is 95 Ron which is equivalent to 90 octane in the US. I will see about finding some toluene. Any issues with running toluene as a additive? (Injectors/ fuel pump and lines) If anyone knows the ratio off the top of their head that be great. If not I will do some digging. I am not not looking to run race gas just get it up to 91 at least if possible.

No risk. It's used to raise octane anyways

Toluene has an AKI of 114, so adjust accordingly to the octane you want


Wouldn't octane boosters be a BITCH to get btw?

Mix some Marvels Mystery Oil in with the toluene and gas. Otherwise it may dry out seals and o rings.

Also, are you allowed to store hazardous chemicals on base?

That's with Xylene Chuck!

Toluene is good to go, but a little/lot of MMO never hurt anyone.
I love MMO and SeaFoam

I have been reading all about toluene for the last 20 mins haha Looks like this will be the option I will have to go with now to find it... Things here are very hard to find not like there is a autozone or walmart down the road. So looks like some local sourcing. Actually they sell one kind of STP octane booster on base which as you can imagine is sold out. I did go to amazon and there is a list of about 10 they will ship to me. But I am sure i would have to use multiple bottles to get enough toluene. As far as hazardous chemicals go, I have a house so I could keep it there. So as long as I get Toluene 100% concentrate I should be good to go? You mentioned paint thinner, is there any additional chemicals in that mix or is it pure? I could have a lot of paint projects in the near future haha

toluene is a paint thinner it is also sold as toluol and a couple other names. The stuff that says automotive grade is what you want which just means there is nothing else in it.

Never seen that, lol. It used to be at Home Depot (they made it illegal in CA)

Just read the back and check the ingredients. I can't imagine 1% of soemthing else would do much. But last I checked... Some of is work at a company with many, MANY scientists... (AHEM, me) and if there is something else in a can you find, just post it up.


And look for Xylene as a backup, you will have to mix other stuff in with it, but maybe it's more available

I ran toluene in my ATV for a couple years with no issues. It does add a sort of race gas smell to it!

As an FYI we can only get 91 here. I really doubt 90 is going to be that bad. I know people that run Z's and G's on 87 and have no issues. One guy on the MYG37 has posted his gas milage for years and makes sure every knows he runs 87. I think the last time I saw he had well over 80k on the car. He swears everyone is nutz for paying for the extra octane. Me I use 91 as that is as good as I can get. If I could only get 90 I would run it and not worry unless I was going to be racing the car.
