Throttle body cleaning for 2014 Tahoe LT

Oh. 93 is premium. That shit expensive haah

What’s chevron 93, and I’m torn between e85 or e87 there’s pros and cons to both. I run e87 currently after running e85 about a month or so. It is flex fuel.

What's the pro to running 87 octane compared to anything else?

It lasts longer than e85 and is supposed to make my vehicle run butter i read. I use e87 with 10% ethanol (actually like 8%)

And I’m not sure. Just what I read is what I know. I meant to ask you

Hmm, ok! I’ll take a wack. What year is yours though?

See my signature below?

Well, there is that. E85 at full strength delivers more horsepower to the pavement but does not last as long. E85 burns about 1/2 gallon more per hour up to about 50/50 city/hwy driving and a full gallon per hour more at 100% highway driving.

Excepting direct injected engines, every car driven by me in 30+ years of driving has performed more efficiently burning 93 compared with 87. Until about 20 years ago, low octane fuels didn't come with the same additive packs that made high test gas so much more powerful but the comparisons today still hold. I always get better mileage and performance running 93 over 87 in ANYTHING, whether it be my weed eater, lawn mower, generator, Toyota 4 cylinder or my LS engines.

Now, one measure of efficiency is in cost per mile. It does not always make sense to burn E85 or 93 octane compared to 87 octane. As for me and my house, we never consider anything less than 93 when it comes to choosing gasoline. It's either that or E85. I might get better gas mileage on 93 over 87 or E85 but the cost difference may not be worth it if the spread is too great. The performance loss and ignition retard is not worth using 87 IMO.

A note on designations. Gasolines today are either E0 for ethanol free or E10. E10 can be 87, 89, 91, 93, etc. E15 is 88 octane and is made up of either 85 or 87 octane fuel plus ethanol.

E85 can be anywhere from 51% to 83% ethanol content. E70 can be anywhere from 51% to 70%! Ethanol is also sold as E20, E25, E30, E40, E50.

Good info! should I try a tank of some 93 than? I can just throw it in with 87?edit: does it clean fuel injectors?

And I see yours is 07? I was pretty sure that there is something different with the relearn in 2014 and later models. Though it’s the same generation. I find that a lot of things in the 2014 are unique from the 2007-2013. I could be wrong. But things like relearn I thought were necessary. At least that’s what I seen happen to some guy on YouTube after cleaning his throttle body, he had to reset the rpm or relearn it or something because his idle rpm was higher after cleaning it

For example the maf sensor is different in the 2014 than the ones in the 2007-2013 those ones have like a screen

It'll get diluted by the 87. Just run the tank down as normal and then fill up with 93. If you are wanting to clean the injectors, use E85 instead. Run 5 or 6 tanks in a row before switching to something else.

no they changed after 2009 i think, not 2013 your 14 is no different than a 2010, 2011, 2012, 2013 with a couple of minor exceptions
you might not even find parts listed unless you search for 2013 because it's one of those years that parts places get confused due to erroneous information so they just stop at 2013 in compatibilty listings.
as for injector cleaner walmart used to have the bottles for .99 cents but since good ol joe it's now like 2.99
so the quart bottle of lucas is cheaper and the 1 gallon is even cheaper than that (per oz), i have been buying the quart bottle and just add 1/3rd per tank full
