Running different grades of gasoline won't harm your injectors. Also, running premium in a car that doesn't require it won't make any noticeable difference unless your car isn't running right to begin with. I personally use premium in my LS because higher grades generally use better detergents, and more of them.thats the thing it doesnt say premium, its nonvtec, so wondered if my injectors were screwed with premium.. as i said earlier
I think detergent levels have to do with the station selling it. Places like shell and chevron have higher levels than arco or safeway gas. But putting premium in your b18b1 will not benefit you.Running different grades of gasoline won't harm your injectors.

That would be incorrect, it's the same across all grades for the same brand of gas.higher grades generally use better detergents, and more of them.
Actually 86 octane was never premium. Long ago and in a galaxy far far away we ran 98 octane as premium and if we had heavily modified our motors, 125 octane aviation fuel.It says to use a minimum of 86 octane, not premium. I was like "Wait, at one point in time 86 octane was the premium?!" I didn't even catch that you said 2000. Anyways.
Non-vTec = 86 octane, not a problem because I think the lowest sold is 87.
vTec = 91 octane.
^^ This.I have always avoided running anything less than the octane specified for any of the cars I have owned over the years. Current price spread in Georgia between regular and premiium is $0.30 per gallon. With our twelve gallon tanks that works out to $3.60 per fill up. That is too little money to risk the damage from engine knock in my GSR. At 220,000 miles it has never had less than 93 octane.
Putting premium in your car is doing zero for it to baby it.I know i dont havta put premium in my teg, but I do anyway because I baby my car and I wanna give it the best. Besides I'll havta put premium in it anyway once i do a gsr swap in a year or so.
From what I understand, the premium fuels at top tier stations contain less ethanol than lower grades.. So if that's correct, then actually it is better for your car. Being that older cars like mine aren't exactly ethanol friendly. Please correct any incorrect information, as this is just something that I picked up from an old friend. That being said, I have a gsr swap, so I only run top tier premium anyway.Putting premium in your car is doing zero for it to baby it.
Shell>all others.St Louis gas is as follows... All i use is shell v-power...
Reg-87
Mid-89
Premium-93 (some only sell 91 for premium... but i dont use these janky places anyways)
That was long ago. The aviation industry uses 100LL for Avgas right now, and even that will be going away soon if the EPA has their way.Actually 86 octane was never premium.
