Running 93 octane in an engine designed for a lower grade doesn't do a thing but make your pocket lighter unless you have the performance computer that increases timing and fuel or other internal mods that require it. But we all know that.
We don't even have 93 octane around here. Even if I wanted the 9ner Mopar chip I would be SOL.
well polka you should know your 5.9 requires premium fuel. also kolak can get high performance comps for cheap. polka I should of known you where a cat lady english teacher by the pic. lol but also the higher octane fuel does help alot or why would we use raceing fuels at the speedways and these days regular isnt safe. I use to work at a gas station they water down regualer and now with the help of corn.... Well lets just say I wouldnt put corn in my car. you never get what you pay for. but I get my 93 or higher octane from sunoco. I get a discount so I pay less than you do for regular. Its alot cleaner aswell. assumeing gas prices are the same. and higher octane gas doesnt freeze as easy. not to mention you get further on a tank of high octane than on regular. polka you kinna seam like one of those guys that thinks oils good for 7k. and holidays are made by halmark. Its aol kolak becareful of crosses sunlight and garlic. lol
ugh back to topic. what do you use for a tune up? results? etc.. or we could keep bickering nit pikkin yippin etc.. talk about mods, differnt cars, engines,grammer, hommosexuality, immagration, taxxes, etc... Vote Ron Paul
Using any grade of fuel above what the stock vehicle is engineered for is useless. Race cars use race fuel because they are "race cars". Regular is not safe? Maybe on your planet it isn't. Are you getting mad because I disagree with you?
No actually lol I think your funny everyone has there own opinion. I like hearing everyone elses opinion or why would I be on a forum? I beleive the v8 magnums are designed for 91 octane. regular on my "planet" consists of ethonal water and a little gasoline. round here we got this place called cumberland farms there gas is so bad itll make your engine knock. We dont get the same regulation type gasoline as yall get in the city. I assume. I prefer real gas not alcohol ethonal and other chemicals. If that was the case whatever you where sayying. then there wouldnt be a plus super etc. there would just be plain gasoline. no vpower no ultra. Im not sure if your aware but even just swapping out the heads on a motor can create a need for higher octane fuel. race cars and regular cars are not all that differnt. they dont have seperate types of motors. even work trucks can have a hemi. would you like to get into the deisel bio deisel high sulfer deisel argument aswell? Im not sure if you notice all that water comeing out of your tailpipe but that would be the h2o in your fuel your feeding through your motor.
by the way I realize this will never get anywhere. this is a useless thread. to many people feel threatened. Its like sayying my dicks bigger than yours. which aparently it is. But I just wanted to know what everone else does for a tune up. enjoy your kitty porn lmao. I wont bother with this forum again. Its not what it use to be.
Octane is related to altitude. So one person's experience is not relative to another if they live at different altitudes, and as seen here the higher you go the less likely stations are to have 93 octane.
My truck does mileage in the high teens, sometimes cruising over 20mpg on 55mph blacktop. Using champion copper plus plugs, no fouling or other bad habits. Parts store 7mm wires and a fairly new cap & rotor, stock replacment. Stock replacement coil that's a few years old. Totally stock engine, air filter, exhaust
Some engines are picky about plugs, others are not. Apparently dodge V8 magnums like champions, but it doesn't mean that they won't run well on other brands too. FYI accel plugs are yellow motorcrafts with a premium price and the only reason to run them is if you need their special shorty plugs because of hedder interference. Not a problem with dodge V8 based on how the plugs & exhaust are positioned.
If you're after mileage change the O2 sensor.
At some point mileage drops off, usually somewhere over 150K miles. The cam, pushrods, rockers, valve seats, and piston rings start wearing and you just lose efficiency. An old iron V8 will usually run for a hundred thousand miles past that point.
Some people are on crack when figuring mileage, never trust another person's figures. My best buddy claims his 4x4 suburban gets 25mpg but when we road trip and I'm paying/pumping it's closer to 17. We have nearly identical big block C20 pickups and he likes to rub in that his truck beats mine by 9mpg. I just smile and nod.
A thread becomes useless when a person asks for information then refuses to accept anything other than the answer they expected.
ohh no foundry dude I appreciate the advise as always. just got frustrated with those who talk crap. Im going by the miles the comp is reading off I dont actualy exspect a v8 to get 17mpg thats why Im asking for what there comp is reading. In reality I would guess 8-10 and 14-16 highway for the motor. not what the comp is guessing. I dont have very much faith in computers. but I beleive they will all read around the same. If someones getting better readings I know there getting better mpg. regardless of what the numbers are. I didnt want to know what I already know what was good for the car back in 1995 but what has worked best now on all brands makes etc.. now. from exsperience. just got frustrated and distracted. How long do the champions last? and you havent had any problems because I look them up and I get alot of people sayying there junk. Like i said before ive had them in my lawn mowers and they dont work too good. But maybe im wrong. as for gas and altitude wtf? no way? all im sayying is look where you get your gas. we dont have quality control round here. if they can buy gas water it down add some chemicals to make a buck on you they will. even the goverment does this with ethonal. thats why people have to add dry gas. Just like mcdonalds and there ultra thin kangaroo burgers. I put the best in my riggs. Ive never heard of regular being as good as high octane. you do get better mpg on it try it sometime. well enless all your gas station sells is regular and slap differnt labels on it.
