Hey everyone,

I noticed last night on my drive home from work, my car feels a lot more rough compared to normal. For instance, when I press the clutch in, it's not smooth but feels tough. When I got home, I checked the oil and it was still on H and the oil color was a darker hazel color. I had filled up at lunch time so when I got home, there was about 20km on the odo and -1 bar from full tank of gas. I didn' think much of this so I let it slide as a one off thing.

This morning, I start up and the car feels fine again. I commute about 40km for work, half way to work I notice the car has that feel again. Now when I got to work, I see that my car has only gone 60km since I filled up and I'm already at 1/4th my tank gone. Since day one, I normally get 415-430km per tank.

Is this something I should be worried about and take the car in to have it looked at?

Thanks!

 

Maybe there is something wrong with the fuel you put in. at 1/4 tank you would normally get about 50 KM further. This is a big hit on your km/gallon.

 

That thought did come up but then I've used this station before and I filled Chevron 91 premium.

Another thing I noticed, the car now runs at a lower RPM. I'm in 5th gear going 60km and it's barely at 2.5krpm on the tach. This was not the case on the weekend or when anytime that I can remember during ownership. Something just feels really off from yesterday and today...

 

My AP1 seems very sensitive to gas, regardless of what brand of 93 i put in. I always use Shell 93, but recently was forced to use Mobil 93 and the car didnt feel right. As soon as i put Shell 93 back in the car seemed fine again. I know its a stretch but maybe your car, for whatever reason, is sensitive to the gas. Also, who knows if the gas you got is really the 91. Gas stations rip people off and mix tanks all the time. i know, i have a buddy whos station has done it a few times.

Regardless, dont use anything but 93. Just my 2c....

 

It is not possible for the car to be running at lower rpm but traveling at the same speed in the same gear unless you have changed the gearing.

Possibly time for regular tune up stuff: plugs, air filter, etc...
