I never turn my engine off at petrol stations!

[matty6660]

I have an RX8 which has the dreaded hot start problem. After about 15 minutes of driving, if you turn the engine off, it won't start for at least 20-30 minutes as the engine needs to cool down. So I have no choice but to leave it running while I pump gas so I can drive off straight away. Otherwise I would block the pump for a long time. And I ain't pushing it over to the side after ever time I fill up!

I know petrol stations say you need to turn off your engine but is that just an advisory or legislation? It can't be dangerous to do this as I have never had any problems. I hope to get the uprated starter motor soon but they're expensive :S Does anyone else do this when pumping gas?

Serves you right for having an LPG conversion.

I don't have an LPG conversion o.O

The car starts just fine if the engine is healthy. I doubt the uprated starter would help this guy out anyway and to be honest if he can't afford a £300 starter motor then he shouldn't have purchased the car without looking into running costs with RX-8's, particularly ones in a poor state of health. The problem with RX-8's now is that their residual values are so low that you have people who should be driving a 1.2 Vauxhall Corsa buying the RX-8 because they want a sports car, but these people aren't prepared for the cost of ownership.

A healthy RX-8 like mine costs me fuel, oil and spark plugs to keep going but at the same time I did things differently. I purchased an RX-8 with a bad engine on purpose and had it rebuilt and had new coils installed.

Oh I didn't know I had to ask your permission before I bought my car.

By the way, the older RX8's don't start when hot even if the engine is healthy and brand new The new RX8's start when hot because they have the uprated 2kw starter as opposed to the old 1.3kw starter in my model. And 2kw starters are on ebay for £100 not £300. You don't seem to know much about RX8's and yet you apparently own one? lol

I imginge the OP's is far from being in tip top condition.

I have no problem with starting my engine when its warm - multiple track days down and I haven't had a single issue.

It's excellent condition with 60k miles. But ALL older models of RX8's have the hot start problem. Even when brand new. Google search will let ya know

Bullst, my RX-8 is an early 2004 model with the original starter motor, i.e. low rpm one. And I got my starter price figure from the most well respected rotary parts website Mazda Rotary Parts:

Genuine Faster Starter - £408: http://www.mazdarotaryparts.com/bgenuine-mazda-rx-...

Compatible Mitsubishi Faster Starter - £276: http://www.mazdarotaryparts.com/bmazda-rx-8-r3--mi...

So, the £300 isn't the exact number but it is in between the two. Anyway, you aren't wrong that several early RX-8's had faster starter motors fitted to them over time but not all of them did, like mine. Which reminds me, I should put an uprated starter on mine as a form of insurance.

Yes I said early RX8's have the old starter the 1.3kw one. I have a January 2004 RX8 with this starter. I'm saying that all models with this particular starter do not start when the engine is hot. Does yours? If it has the original starter, it will not start when hot.

Also you might want to shop around if you're looking for a starter motor:

£92 on ebay mate. Sod that £408 lark.

What the OP is saying about the older RX8's all having the hot start issues on original components isn't true. Some are still going fine.

He's talking utter codswallop.

^ coming from someone whos probably never even driven an RX8. Look why am I the one getting persecuted for the previous owner not looking after the car properly. My original question was asking whether I could leave the engine running while filling up. And I've got my answer now so as far as I'm concerned this thread might as well be closed.

Your just full of TrueFacts, aren't you?

If only I could own a rotary powered car, I might become a little more enlightened as to what their foibles are. Sadly, 'tis but a distant dream.

Let us know when you get the results of that compression test, huh?

Edited by FD3Si on Friday 19th September 15:44

Sod the compression test. There's loads of videos on youtube where people have put the uprated starter in and done like 200 miles and turned the car off, and it starts straight up again. That's good enough for me. Besides, if it has lost compression, I hardly notice it. The acceleration is like nothing else I've ever driven so I'm not bothered.

I like the part where the OP says there is also a 2.6L version after someone corrected him saying it's a 1.3!

It's hilarious seeing someone know so little after thinking they know so much. We've all been there at one stage though.

why does it say 2616cc on the log book

It's definitely a 1.3.

"The actual "full" displacement of a 13B is 3.9L, but that is from 1 full rotation of the 2 rotors. **But** 1 full rotation of the rotors turns the crankshaft (or properly called an "eccentric" shaft on a rotary) *3* times.

Since a piston engine rates it's displacement based on 1 rotation of the crank, Mazda follows suit and rates the rotary by 1 crank revolution... so 1/3 of 3.9L is 1.3L.

From a power output perspective it's really a 2.6L as you get twice as many "power-strokes" from a rotary then from a piston engine. This is why rotary engines are so powerful compared to its size."
