The vehicles engine map will be the differance. If you are using a throttle body spec for a differant set up then it is bound to be wrong. The TPS may also vary on model to model.
I think you need to do a throttle position sensor recalibration (reset). (NOTE: I will post several different adjustment versions. I believe the top one is what you need (for a K8 engine), but will include another four depending on your engine.) To do this for your vehicle you need to follow the steps below, depending on whether it is a stick/auto and ...
I think this could definitely be cause by bad fuel. It would probably do good for you to put a bottle or two of gas treatment into your tank. Put it in and run the fuel down to near empty (not all the way, but run it down to about an 1/8th tank), then fill the tank full with gas from a known good source. You may ask how do you figure out which gas is good? ...
When you turn your steering wheel, even ever so slightly: as the tyres turn the tread on the tyre 'shuffles'. The more your tread shuffles, the greater the tyre wear. The manufactures recommended pressures will give you the optimum performance and wear from your tyres. Under inflation allows the edges of the tyres to take all the load and shuffle-increasing ...
Recommended values give you the handling and tire wear that the manufacturer intends for the vehicle. If you increase above that, the contact patch decreases, giving better gas mileage, but you start sacrificing handling and causing abnormal tire wear.
I’ve heard folks claim mileage gains by running their tire pressure above the manufacturer’s recommendations. In theory, that makes sense: With more inflation pressure, the tire bulges in the center of the tread and creates a smaller, skinnier contact patch with the road. This should mean less rolling resistance and increased mileage. we know under-inflated ...
When your tyre pressure is lower,there is more rubber in contact with the road, so your engine has to work a little harder to keep you moving forward.
Your logic is way off. You should change your oil and filter at the manufacturers recommended intervals, with an oil of the manufacturers specification. The manufacturers cover many many miles under many differant conditions to decide a specification and in most circumstances the specification cannot be bettered for the intended use of the vehicle.
