Well something is decreasing my RPM, making my car run smoother, and giving me better MPG. This happened right after my synthetic oil was put in, and im pretty sure that synthetic gives you better MPG, and makes your car run smoother. So where do you suggest the other factor is coming from?

Your imagination, like every other stupid thing you come up with.

I saw that coming. But dont worry. Im not a jerkoff like you, so I got notihng to worry about. The car runs great, and you can take your own advice.

so wait... i'm not understanding something here.

old oil is dirty, and that could make the engine not run as well (untill it dies eventually). so, why would that not result in less torque being made at the same RPM? and if less torque is made, that's less force to push the car forwad. wouldn't that mean at the same RPM, old oil would make less hp, which would result in less speed?

that was my (basic) understanding of how changing oil can be beneficial. so if that's wrong, WHERE is the fault in reasoning? but of course, notice i'm not saying HOW much of a difference in speed (or rpm to reach said speed).

I'm changing my oil soon, what is the best fully synthetic oil I can get? Castrol?
I was also wondering about which would be the best Transmission Fluid and flush kits were?

oil is what helps lube your engine, it helps the parts from creating heat through friction. not changing your oil results in messing up the inside of your cylinders b/c of friction between the piston and the walls of the block. I think this can lead to overheating and/or minimal loss of power, but i dont no for sure. I do know that different grades of oil will not substantilly increas or decrease the performnace of your engine, as long as your within the right specfications laid out by the manufacturer.

oil dosent increase the speed of your engines revolution, its decreases the energey required to make ONE revolution, thus decreasing feul consumed, thus producing better feul economy, but not more power.

and newyorker, maybe its just your looking at the Tach at a different time, dipshit, your not accounting human error into any of your thinking, OIL DOES NOT DECRASE RPMs BY 500RPM get over it

old oil is not that bad for hp and tq issues, it mostly a wear and tear issue, the main reason for changing oil, this is my basic understanding from observation, research, and anything else ive seen/hear/felt

ask hobo for more, or chrisV or any one else that probably knows more

You have this new oil for like a week and this is already so noticeable?

Yes. I already ran a full tank. The car ran smoother as soon as I rolled out of the mechanics parking lot. I hit 60 on philmont and the car didnt keep a high rpm like before but instead ran at a lower one. Gas milage has improved. Now I drive 60 and it feels like im going 40 because the engine keeps at lower rpm and its just quieter and smoother.

you talk about knowing cars so much but you had to go to a MECHANIC to get your oil changed? comon, i didnt even need help the first time i changed the oil on my car... geeze


and going 60, and having it feel like 40, is just asking for an accident to ahppen b/c you dont know what your speed is

Itl take time for me to get used to it. The only reason I went to a mechanic to change my oil was because there was still snow in some places, it was really really cold outside, and it was wet. I didnt want to run my oil over its deadline, so I just went to get it done. My first oil change i did on the car I did myself (using grandpas tools). The sparkplugs I changed myself (grandpas tools). I can do my own oil changes, and prefer to do it myself, but this just was a case where weather didnt provide me with the right circumstances to lift the car in 40 degree cold.
