No announcement yet.
My 18is is consuming way to much fuel...

For me it isn´t required to have a catalyst, so i just removed it.
this will free up some horsepower too :)
offcourse you can replace it. but those things are really expensive

but i can´t say if that´s going to affect your engine performance & noise or not
regarding the fuel consumption, more news... My mechanic used the machine that detects errors in the ocb, and discovered that it was accusing an error that wasn't wiped out previously. So he wiped it all. Let's see if it makes any difference

Any update?

Yeah sorry, i always forget to come back and report.
The fuel comsumption did drop, to 9,8l/100km. Much better, but i still it's too much, for the kind of driving i do (30% city, rest is crusing at 90kph).
I did put on some new 16" wheels after that and the fuel rised to 10,2l/100, don't know why...
I really don't know what to check for, what do you guys recommend?
Furthermore, my next mod is putting a conical air filter, and that should rise the fuel consumption even more right?

Cruising mileage can be impacted by total wheel/tire height. In that respect it's all about revolutions per mile.
A cone filter could actually improve mileage in some cases as it often draws warm air in to the intake versus cold air. Thus a less dense air charge means less fuel injected/less total power. It's all dependent on your specific circumstances of course.
In any case, there's something seriously wrong with your car or engine when an M42 is getting sub 18 MPG. What fuel are you using again, do you carry a lot of stuff in the car regularly?

It still is high anyway. I use 95 octane european gas (don't know exactly what it converts to in "american" octanes, but i think its 91. I don't carry nothing at all in the car, just me and half the time a single passanger. I really can't find whats wrong, plus it's a shame for an engine with just 130000kilometres....

Welp, if you do find the problem let me know....
have you done a compression check on your cilinders?
