I knew s.one would say that. For wankel i heard that this is more critical, is it?

 

PS: I dont warm up, i do slow down before i reach the destination..

The wankel normally runs turbos, but the problem is that if you just shut down, the heat has nowhere to escape from the driveshaft and it swells and damages the seals. When I used to work on steam engines, we had to mormalize for hours, to avoid hogging and sagging of the turbine shafts.

Yupyup. The Renesis engine is also prone to foul the plugs if just briefly started and stopped again. Just like my KL :)

 

I've also read somewhere that the Renesis engine is designed to run on a heavier weight oil than Mazda recommends. The recommendation is a result of environmental issues; thin oil reduces fuel consumption enough to save Mazda from paying penalty taxes or something like that. And apparently it is cheaper to swap some engines than paying said taxes... Strange world we live in.

Of course they want you to run lighter oils, then the engine fails sooner... it is a maintenance business.... they do not sell cars to just make profit once.... they sell cars so you will constantly maintain it.... and they hope it will be exclusively with them. They offer warranties as it is cheaper to fix it after than to make it right the first time, and it also "trains" the customer to return to the dealership for any issue....

Taxes here on a vehicle are only based on the sale price....

:hmm: No taxes based on pollution? I'm not talking purchaser taxes mind you, taxes for the manufaturers. Oh, nevermind ;) Let's just conclude with rotaries liking heavier oils than Mazda recommeds. I am finding it harder and harder to trust these guys... Ain't no Mazda techs gonna mess with my Xedos anymore :thumbdown:

In puerto rico they have insane car taxes depending on the type of car. Luxury cars have a tax, performance cars have another tax, coupes another all different amounts. For instance an M5 over there cost about 100k base because its considered a performance luxury car.

as far as I'm concerned, every car, especially rotary and anything forced induction should go through a cool down, don't just pull in, park and turn it off, letting hot oil go through everything. let the car idle for a few minutes, give the oil a chance to circulate and cool down a bit. When driving the millenia I come in slow, then inbetween idling around to get the garage parking just perfect and leaving it sit another 2 it has worked well for me

This has been discussed in many RX forums, and enginehead conversations... of which BHR is not usually welcome :lol:

I have never been banned from an RX forum

 

and I agree with camel, well except for the flooding part, if you've got fuel injection you won't have to worry about that.

 

I NEVER under any condition start any car then turn it off again a few minutes later, if I start a car its going to be driven or reach operating temp before it goes off again.

 

Generally speaking whenever I run the cars hard I take it nice and easy the last half mile or so getting to my house, and even then I still let it idle a good bit before shutting it off.

The reverse applies to warming up; no hard driving at all until full operating temperature - the transmission needs to warm up too and only light driving can achieve that.

The RX8 has fuel injection of course, but still tends to get flooded if repeatedly started without being warmed up. Like I said, just like my KL, which also is fuel injected. I don't know about the KL, but it is a known issue on the RX8.

enver once been an issue on any fuel injected car I'v ever owned, even though I never do retarded shit like start the car, move a few feet in the driveway, turn off, move again, go get mail etc like other retards, (5.2 v8) getting flooded maybe once

 

happened a decent amount on my old tractor though, annoying as fuck.

 

when it comes to start up I let all my cars idle for a good 30 seconds before going anywhere, and drive slow. With the millenia since it sits a bit longer I give it about 2-3 minutes before driving, and drive hella slow, nothing rough, low rpm's, right on shift points.

55hp? what the hell kind of grass do you cut? That thing was around 18 or 20, even the newest tractors are about 22-26, commerical ones are around 28 at the most.
