Here are a couple of things I've found that are very useful, and smart1) If your truck runs OK on regular gasoline (87 octane)and you get just a little pinging climbing hills, or when towing,provided you have dual gas tanks just fill one with regular, and the other with premimum (91octane or higher) and switch tanks as needed to help your engine run well under all conditions.
(2) I keep an electric cooler in my truck to keep regular grocery store items cold, as I sometimes shop for my Mom, and my Dad, and sometimes for my Wife & I, and don't go directly home, these coolers (made by Igloo, and Coleman)will keep things at between 38*and 44* cooler that the outside air is.

 

Well the first one doesn't make much sense because the fuel overlap will just mix them together anyway. Coolers are cool though.

 

I sometimes use super unleaded 93 octane when towing. I switch it in (2 tanks) well before the hill, and have found I get an extra 3mph going up the hill. It also works really well for drag racing (but you never heard that from me...)

 

Hey Supercab, I see you're a fan of the Bucket lady! Uh excuse me, Bouquet!

Yes, I have to confess I, as well as my Wife are big fans of "keeping up Appearances" we started watching a few years back, and now own more than 1/2 of the episodes that were made.

 

Mr.221, Please explain the "fuel overlap" to me, I was under the impression that if and when you changed tanks that one tank was completely cut off from the other, provided the truck doesn't have the dreadded backflow problem.

 

When you do switch tanks the other one is completely shut off. What he means is that it'd take a minute or 2 for it to get pure 93 octane... because there is still regular gas in the fuel lines... So you have to use whats in the line first.....

 

I use the two tank trick when I tow my 8,000# trailer. 87 in one tank 92 in the other. Works just fine. When I get near a hill I switch over to the premium gas. Since my 460 engine slurps gas so fast, I doubt that the miniscule amount of gas in the lines takes more than a few seconds to be used up. I have not noticed an appreciable lag between switching the tanks and the cessation of pinging.

Just some wild guessing/math... My truck gets 8-9mpg while towing. Assuming there is maybe 2 oz of regular in the lines... It would take my truck about 8 seconds to slurp up that amount of fuel assuming I am going 60mph. Since I assume I would be on a hill when I switch tanks, the time woul dbe shorter since my mileage goes down on hills. So theoretically I might notice a lag but practically it has never been an issue.

As far as those coolers go. they are OK but they only cool about 40 degrees. If the cab is 80 you are probably OK. If the truck is sitting in the sun the temp will be much higher and the cooler less effective. It also takes a looong time for these coolers to get to temp. Best to make sure the contents are cold before putting them in. On long trips, the cooler keeps things cool enough that say a soda is acceptable, but they are rarely icy cold the way I like them, like they would be with an ice chest. Good thing about the coolers is you don't need ice, so as long as you got battery you have cool. Note that these things suck down batteries fast(mine pulls 10 amps, eeets a beeg one), so best not to leave them running with the engine off over nite.

Just my opinions,
