Supercharger

*sigh* if only I could be easy on the pedal…

 

Yeah. But a supercharger with 93 is a no brainer. Who's gonna drive around with a pinging s/c on 89?

 

TRD recommends 93. No reason to use anything else. Its only 20cents more a gallon.

 

91 all day

 

My point is that the supercharger does not make the engine more efficient on 93, it just calls for it and so happens that 93 may give better mpg.
However I have seen no difference and 20c/gal adds up to a lot in one year. More than you are saving.

 

Ok yes 93 octane would generally give better mpgs and my point is that those with a s/c wouldn't run 89 cause that creates engine knocking, pre ignition, you're increasing cylinder pressure thus needing higher octane rate

 

I don't think running anything less than 91 is healthy for the engine not to mention the S/C.

 

No guys I understand not to use mid or low grade gas in a charged engine, I was just saying that people with normal engines can run 93 as well so I just wouldn't call it a perk of charging. Just more of a forced good habit. But like I said I don't think the price is worth it, and I know this is not typically the case but I've seen shell v power for 3.75 when regular was 3.10.

 

alot has to do with ur elevation.

The n/a truck will run on 87 but for peak performance and the ability to add more timing (I assume), toyota advises 91

blown= 91+......no exception

 

James...is that you?
