No it doesn't,it's going to get the same milege all the way through the tank.What you're seeing is the float level takes longer to move off the full mark,as you have to burn some fuel before the fuel level starts to move downward and actually show on the gas guage
Follow BT's advice in post #18,and it doesn't hurt to use a small amount of anti-seize on the plug threads,and a small amount of Di-electric grease on the porcellin portion of the plug,don't carried away with either though
^^^ THIS!!!
We have been moving stuff from New York State to Florida. I said we probably have at least 500 pounds in the trailer on any given trip down.
Not really. Some will say any time you're towing, others will pick an arbitrary number and stick to it.
500 pounds? you can fit three times that in the back of your truck and never use the T/H option.
The owner's manual call for 89 octane for the 5.7L Hemi 87 octane is acceptable but may hear light ticking noise.
We are very conservative. I’m a life NRA member and a bow hunter. As much as despised the Cuomo’s this hag is worse! It’s been a long time leaving! Florida is a much more a Free state
actually, most southern states are a lot free-er. I felt like i was released from prison and i found my freedom moving down here. The only complaint I have is the heat and humidity! It takes a while for my northern blood to adjust....
I think I used top ones from NHL and felt a difference with performance. We worth the expense. O² sensors are along exhaust, should be 2 on each side, passenger and driver before catalytic converter. Weird in my case, I had a 2003 2500 5.7 but only had 3 O² sensors, mechanic theorized that the truck, one of first built in 2003 had been adjusted for a 5.9 gas engine exhaust system that was probably left over from the 2002 2500 gassers. Those had 3, 5.7s were designed for 4. And one more thing, when replacing one of the wires of the sensor became compromised so even with new sensor the CEL was still on. Had to find replacement connectors and that fixed issue. Be gentle with the wires.
No, no it doesn't. The gas mileage stays the same. Maybe the fuel gauge goes down a little faster because of the geometry of the arm, but the actual fuel useage or MPG does not somehow change.
The number of O2 sensors depends on the configuration of the exhaust and how many catalytic converters it has. It has zero to do with whether the engine itself is "designed" for it. A typical V-8 (or V-6, or anything with two cylinder banks) will have an O2 sensor on each side for each cylinder bank. These are called the upstream sensors and provide the primary feedback to the ECM for how much fuel it is supplying to the engine. Basically controls how rich or lean the engine is running. Since there is one for each bank you can control how much fuel independently goes to each side to help optimize performance. Any additional O2 sensors are generally called the downstream sensors and located after any catalytic converters. The primary purpose of these is to simply monitor the cat and make sure it's working as desired (reducing emissions) and have very little to no feedback to the ECM in regards to adjusting the fueling in the engine. If the exhaust Y's together into a single pipe with only one cat, you only need one downstream sensor. There is no reason to have two downstream O2 sensors unless you have two cats.
When towing or working the truck use the recommended mid grade but if not towing anything and just driving around (work, home, errands etc) you'll be just fine with regular 87 fuel. Premium fuel is just a waste of money if your vehicle doesn't specifically require it.
