Overfill is not a good thing to do, but in a rotary it's not really a bad thing either (as it is in piston engines where cam's will froth excess).

3k and worry free.

 

The time between when you have to add oil varies a lot between cars, as well as with the season, temperature, driving style, etc. Mine doesnt usually ever need top-offs between 3000 mile oil changes. So...chill....

 

Does anyone ever get the "light" mine tends to know whenever I'm within half mile from home then turns on. I check the dipstick and it's about the Half mark. I added oil, it goes away for now. So, does youuuuuuur light come on?

 

Mine has never got low enough to trigger the light. But I check it at every fill up and top off accordingly, so that's why.

 

good for you lol the new 8 FTW.

i had to add oil to my once a while, i check oil every time i fill up gas. which is like every week.

 

is petrocanada's 15w40 non synthetic oil is good for 8. and also is also good for all kinda weathers?

 

That's a horrible viscosity for cold weather.

Stick to 5w-20 or 5w-30 (or possibly 0w-20 or 0w-30 if it is going to be REALLY cold)

 

Never had the light trigger. I usually check it every fill up.

 

Im usually good at checking, maybe it's a good idea to carry a vial of oil around my neck. For some reason it's either full or empty, lol

 

in the 8 months i've owned my car i've had to add oil.....

twice. (it was a huge ordeal, lemme tell ya)

 

the thing is where i live in winters its not that cold ...but in summers it gets really hot like around 35-40 C'. so i was confused abt which kinda oil shud i use and plus i dont have any mazda dealership here i got this car imported from japan.
any suggestions abt the oil.

 

Well, if you want to tell us either where you live or how cold it does get there, may be can help you.

 

Pakistan .....well on average the temperature in winter is around 3-4 ..and in summer it shoots up to around 40..

 

using a high viscosity oil makes you get worse gas mileage by a little bit, I see little reason to go so high unless it's very hot out. if you use the 5-20 you should be fine.

My engine seems to use a lot of oil, close to a quart over the last 1000 miles, and I'd rather it used more than less to be perfectly honest, cats are cheaper than engines. I do tend to run the engine in the 3-4k range tho even when cruising, I feel like I'm stressing the engine a bit going any lower since there's so little torque.

I'd run premix in my gas if I were you soap, just for ***** and giggles if nothing else. oh and i'm paranoid about my engine since it's my first rotary, you might want to take that into acount when listening to me.

 

Dealerships overfill the oil on 8's. It's taken about 1.3k miles for the dipstick on my 8 to register a quarter of a quart below full since my first oil change from the dealer.

 

I remember when I went for an oil change, when it was all said and done, I asked what type of oil they put in, so if I needed to add some, I could add the same oil. They told me they put a synthetic and non synthetic blend in. I was an idiot for not asking beforehand. I got pissed. The book says not to ever use synthetic, and I got worried =X

 

What is premix? When do I add oil? I'm thinking of a new exhaust, which one is good? I heard that the K&N Intake gives me +20 HP! Is that true? What kind of oil do I use? Is our car turboed? Someone said my car came with pistons, is that true?

 

yeah mazda made you a special one with pistons

 

Exactly. Viscosity is a measurement of flow resistance, higher being more resistant.

5w-20 is recommended by the engineers who designed the engine and its related systems, and that's what I use.

 

i add about a quart of oil every 1000 miles lol i drive mine hard...

 

fix'd

Also, for what it's worth, the '09s seem to be using oil fairly liberally.

 

rather liberally then not enough...

 

Don't sweat the petty things;
Just pet the sweaty things!

 

Indeed, and I now plan to go to 5w-30 upon the end of my 8's hibernation.

5w-20 is recommended by the engineers who designed the engine and its related systems, at the behest of MNAO marketing people who were concerned about mileage figures and emissions, and that's what I use.
