91 Gas Necessary

sbikes · 09-22-2006, 02:54 PM

I found some specs for the 05+tacos and saw that they recommend 94 gas. I wasn't to excited about this since i just ordered my 07 taco and gas isn't the cheapest thing to buy these days! I was wondering if anyone is running there 05+ taco on 87 (unleaded). Will it harm my truck or affect anything??

You do not need 91... I noticed no difference from 87 octane to 94 I even used when I have my Tacoma. Just goos ole 87 octane and you will be fine.

Good to hear, so i guess you haven't noticed any pinging sounds coming from your engine. I heard putting lower octane (then recomended) can take its toll on the engine over time since it takes less compression to combust.

I use w/e I feel like at that moment... Usually 87. I notice NO performance gain from 87 or 94 octane.

Recommended, but not needed at all. The computer will adjust for any reasonable octane. I say reasonable, because it probably can't take 115 racing or anything like that.

94 octane? I'd never use anything higher than 91, unless you want waste money.

on the '05 and newer tacoma, we have a knock sensor and vvt. you can run almost any grade octane. but, low octane will cause the sensors to retard timing (reducing a little power efficiency, and mpg). i have an auto trans, and it was noticable with the cruise control on.... trans would down shift, sometimes multiple gears when not necessary. i started using the mid grade octane, and on the same roads the down shifting has greatly reduced. you may not notice the engine timing being retarded when driving a manual trans...
