Well,

I always wondering how come?

Always talking for performance in a straight line. How come every time I full up or almost full my tank the car seems to pull stronger?

Is it related to the fuel pressure ? Is it placebo? I would expect the opposite because a full tank means extra weight which means lower performance !

I notice that too but maybe it's just my ego.

Your butt dynos are broken.

Theres no scientific evidence I'm aware of to back that claim up....

It's magic I tell you! MAGIC!

^ apart from the magic do you think it is placebo? Do you think that has to do with fuel temp when you fill gas from a gas station. What a about fuel pressure?

chetrickerman

i think its your butt dyno, as ike said

I used to think my car was faster right after oil changes, but it wasnt. I think its just in your head IMO

chetrickerman

along with synthetic oil makes your car go faster

^^youre not using synthetic oil, just being sarcastic right?

chetrickerman

no, i use synthetic, i like it, so does my engine

I notice my car always seems very perky right below the 3/4 of a tank mark, and right at the last drop of gas. At the mid tank mark it seems kinds lazy, the full tank and 1/4 tank are above the mid tank but not as perky as 3/4 of a tank. haha, make sense?

chetrickerman

you study that too much, i think you need to pay more attention to the road. jk

isnt synthetic terrible for the engine, my dealership tells me that synthetic or 5w30 will void my warranty and tear apart the engine because synthetic breaks down at high temps and becomes too thin of oil for the rotary engine.

chetrickerman

haha, stupid dealers. i use royal purple 5w30, and i havent had a problem with it yet. i will switch to 10w 30 in the summer for thicker protection. a little rule of thumb for you. thinner oil in the winter, thicker oil in the summer. nycgps also uses synthetic, along with hundreds of others on this site. I dont think it will void your warranty either

there are 21 pages in a separate thread that is a sticky thread no less.

https://www.rx8club.com/series-i-tech-garage-22/cumulative-synthetic-oil-discussion-52856/

try checking that first and then come back or just do a search and find it has been discussed countless other times.

well, excuse me guys for not knowing the forum inside and out before each post, and excuse me for using the owners manual recommended 5w20 and asking about the cons of synthetic. My bad, ill do better next time

dont sweat it. the oil debate is a huge one. staunch supporters are either side.

then after you selected dino or synth. then you are allowed to get into debates on what viscosity.

:P

also, my car seems to pull stronger when i leave the gas station. mostly because i want to use a little of the fuel i just put in the car.

chetrickerman

dont take offense to what he said, its just that the synthetic oil myth is brought out a lot

i just dont like recieving smart *** comments, i have a bit of a short temper, youll have to excuse me

My car is definitely faster after I good wash, when it's looking nice and shiny.

chetrickerman

yea, the wind realizes how good it looks, and flows right over it

now it really is. its drag coefficient is reduced. especially if you wax the car. then it becomes like a slippery little bullet!

If I remember correct gas weighs a little over 6lbs a gallon. So I don't really see how adding 84lbs to your car could make it faster.
