    Well I always use the middle grade because I then feel like I'm taking extra good care of my truck but yea and I also always use fuel system cleaner... And thanks!

    I use regular, which is 85 here. We are at 8000' so our octane ratings are low. Seems to do fine. I ran some mid-grade for a while, but couldn't tell any difference in power or milage. My assumption is that if the octane was too low, the engine would knock, the ecm would then retard the spark, and both power and fuel efficiency would be effected. So, I think regular is working just fine.

    False, you only need a higher octane if your engine is pinging, knocking or if you're boosted. Higher octane in a gen1 Taco is just a waste otherwise. Just go by what is recommended in the owner's manual and you'll be fine.

    I agree that 87 should be fine, but if I were you I would experiment. Fuel is different all over the country, due to octane levels, ethenol content, etc. Try a few tanks of each octane level and see if you notice a difference. I tried 89 octane here in Reno, which is about 3,500 ft above sea level, and didn't notice any difference. I went back to 87.

    You don't have 93 where your from huh...

    I use 87 in it. No need what so ever for these trucks to run anything higher. There are also no benefits on running something higher in tacomas unless you boosted.

    89. burns longer than 87 but not as expensive as 91.
