Mid-Range 89 Octane Fuel - Who buys it?
Posted on 8/7/17 at 10:30 pm
Posted on 8/7/17 at 10:30 pm
I was filling up the work truck with 93 octane tonight and realized that except for after hurricanes, I have only ever bought the cheapest (87 octane regular) or most expensive (92/93 octane premium) gasoline--depending on my vehicle.
Who are the people who demand 89 octane mid-range? Or is 89 octane just our collective, de facto hurricane stockpile of fuel?

I've always bought the cheap gas. I do only buy from name brand companies like Exxon or Shell but still only the low octane.

I have never bought the middle grade. It's always regular or super but I could probably get away with the middle grade for my vechile.

My lawn equipment and jetskis get 89 oct. My F150 does during cooler weather since the tune a bit messed up and I'm not giving it full boost anyway. If you have an older vehicle that pings a little on 87 then going up to 89 is a bit cheaper than 93 until you can sort out the issue.

Some engine manufactures require 89 octane....for instance the mid 2000's vintage Dodge 5.7 L Hemi

I run 89 in my old Chevy around town or 93 if I'm on the highway running hard.

Does your employer know you're wasting their money?

Kind of a dumbass reason to put premium fuel in a vehicle that doesn't need it.

Does your truck specifically say that high octane is required (or even recommended)? If not, you are just throwing money away.

Why?

It's a 69 vette, yes its recommended and no I'm not throwing money away.

Some egghead somewhere did a calculation which showed that the extra mileage we get from premium reduces the time spent filling the trucks sufficiently to "cover" our hourly pay. Stated more simply: It's overall cheaper for the company to use premium gas in its fleet.

I don't buy the egghead's logic, but I keep Ole Bessie purring on Exxon's premium 93 regardless.

It's all the same gas with different additives

Those whose vehicle pings on 87 and doesn't on 89.

93 vs 87 will yield the same mileage.
Now, non-ethanol vs. ethanol, then there are mileage differences.

For the same price as 89, you can mix a tank of half 93 and half 87, and make 90. 89 is a complete scam.

The only other reason to go up in octane, when it comes to name-brand fuels at least, is to take advantage of increased detergent additives in the fuel. I fill up on a tank of 89 or 93 Shell (with a good helping of Seafoam or Techron) every few months with my beater Ranger. Seems to clear up a gummy injector that sometimes causes the truck to have a sluggish start when it sits for more than an hour.

The manual for my wife's Maxima specifically says to use 89 octane.
