Not ALL dealerships recommend 87I got my '07 in August and the dealer told me then, and repeated it several times on subsequent visits, that 87 was recommended by all the dealerships.
Over the past 12500 km, I've burned only 2 tanks of #1 gas, and got no better mileage than with the normal 87 I use. I'm learning to keep my foot out of it, to keep my revs below 2500, and for 8 months it's been a carefree experience.
I disagree, but thats what makes TS so great. We can both be right In our own worlds.:tu:this is an old and extensively covered topic go look back in the threads about 6 months and you will find all the info you need (and then some). Long and the short, nothing gained by running prem. I haven't run prem for about 10000 miles, no difference. Sorry Musta....whatever you called yourself, prem doesn't matter on this truck. Other cars do need it, just not this one.
It's exactly the same. The 1GR can run on 87 octane or higher. Toyota recommends 91 for best performance, however. With any octane, the ECU will determine how far it can advance the ignition timing. Obviously since 87 octane is more explosive, the ECU cannot advance the timing as far as 91 octane and the knock sensors actively detect pinging or detonation. Since 91 octane can let the engine achieve more timing, it creates more power, therefore, 87 octane runs the timing retarded since it cannot achieve the maximum amount of advance the ECU specifies. As the compression ratio of an engine increases, the more performance you'll lose between 87 and 91, but since the 1GR only has a 10.0:1 ratio, it's not too terrible.Is the FJ engine not the same as the Tacoma?
