Oh ok. Well, I believe that the engine is not tuned up well in general. It's probably running rich. I can sometimes smell raw gasoline at idle. I thought that it determines the mixture based on air intake temperature and intake air pressure. However, I don't see how to fix this if everything seems to be within normal values. I checked with a scan tool. Is there anything else I could check?

So, it's problematic only if it lights up?

Coolant temperature sensor is good. I'm not sure how it would affect oil smell. Also, a year has passed since replacing the coolant and it didn't move a milimeter. So, everything about that is good. I noticed the gasoline smell when I went to randomly check my oil level. But I remember noticing that the level is too high on the dipstick a few days ago when I changed the oil, so that's why I'm also asking if this could cause the smell problem. Could it be a bad fuel injector? Also, my car is often driven in the city and short relations. Is there something else I could check to gain more data?

I didn't put it in Fabia mk1, because I thought it's a general car topic. Still, my main question is about the gasoline smell. I'm not sure whether it is normal.

I checked when barely warm, because otherwise oil is sticking to the dipstick and I can't see properly. But after 5 shots I can read it. I've seen what's the max, and I'm telling you that mechanic put too much (1cm above a point). I was wondering if that could cause any damage that would contribute to gasoline smell in the oil. My main concear is whether this is normal or not. Thanx!

I was wondering whether you can smell gasoline in your oil. I haven't noticed it before, however I wasn't really smelling it that much. I drive my car often on short relations. The dipstick is very difficult to use in my car because oil is all ower it, but I believe that my mechanic put too much oil few weeks ago (about 1cm over the line) . Could that be an issue?

Interesting. I have seen that many newer cars have ECU restriction if EGR is disconnected. In my case there was no noticeable effect on performance, but there is a noticeable effect on fuel consumption. It's not much, but it's measurable.

I think that the best way of testing this is to put a measured amount of fuel in the car and just measure the distance traveled until it's spent. I don't trust the mpg meter that much...

I have to add on the topic that so far EGR delete had significant impact on increasing mpg. It should be also important to note that my EGR didn't seem to have any issues prior to this test. This is, however, first 140km and I will keep testing it for at least 1000km because there could be some error. I also have to add that in that small period of time my car has been idling alot (because we had earthquakes) and it was turned on and off many times.

Thanx! I have already used this chart and that's how I calculated that the rim I want to buy will stick out by 1 inch (based on et number and width). I am not planning to go with ultra thin sidewall, as I will convert it to new dimensions accordingly and make it as thick as 165/70. With higher width, the thickness as a number can be less and remain the same because number 70 is percentage of number 165.

Made a mistake, it is Skoda lol

Thank you, that was actually what I needed. I'm not sure, but I can assume that Skoda would behave similarly to this Seat. I will be looking for Skoda/VW 6.5 max then.

Thank you for the support.

Sorry man, but I am fully aware of the physics behind this, coefficient of inertia and weight distribution. This topic has nothing to do with increasing the efficiency of the vehicle. I am looking for a new set of wheels that I will occasionally use for tests. I will be buying multiple sets of wheels with different weight distribution characteristics. I am not looking for extra power on this engine, and I wasn't asking for it. I'm a chemist with quite a bit of experience in programming and automatization. I'm new into cars, but I'm not unaware, and I make sure that I search for every bit of information I can find on the topic. As an addition, I try to ask questions to clarify things that require experience. I wasn't looking for what's optimal, I was looking for what will fit. I am not sure how you managed to misunderstand this topic, and I am very sorry for that. This is not my first time doing a project, in house, with limited resources. I can't go into VW and ask them to do testing on their vehicles without any prior knowledge or experience. When I want to do something new, or work for a different company, I acquire new skills on my own and get there. Can't stay in one place for a long time, because my hobby is optimization. And there is only so much you can optimize in a company before it becomes boring. If you feel like I'm wasting your time, don't react to the topic. Also, don't waste my time with useless information I didn't ask for. You are a type of person who just waits to "punk" someone he thinks is clueless. You will lose all your friends that way.

I have adjustable shocks. I want to get rid of sidewall flex in the cornering.
