When does petrol and diesel become resinous?
My driving instructor told me that gasoline becomes resinous if it's left standing for too long… is that true? And is it the same with diesel?
Why is the combustion engine always made of rusted sheet metal and not sustainably made of stainless steel with a lotus effect?
Especially with the gasoline engine, everything is always covered in oil during repairs. The exhaust system is also always oxidized and rusted. Would it be possible to produce the individual parts using a 3D printer with real, high-quality metals?
Engine oil Audi Q2 1.4 TFSI, 110 kW?
Hello everyone, Last night, I witnessed a heated discussion between two friends of mine, both of whom drive identical Audi Q2s, one from 2017 and the other from 2018.

No spark on your lawn tractor?
Hello, I have the following problem with my John Deere lawn tractor rx 75: the engine turns when starting but does not produce a strong ignition spark.

Is it normal for a car's performance to decrease when the air conditioning is on?

Briefly about the car: Seat Leon 1.4 TSI Year of construction 2009 182,000km No major problems so far. Do you think it would still be…
BMW 4 Series – 430i or 430d?
Hello, I'm interested in the BMW 430 (f36 facelift). Since I've only driven an older 318d so far, I'm not very familiar with the differences between diesel and gasoline engines.

Hello, I wanted to modify my Keeway Ry8 so I could mix it myself (gasoline and oil directly into the tank). What do I need to do for that? What kind of mixture? 1:25? 1:50? Thanks in advance for your answers! Greetings Leon
Compression tester shows lower value due to hose?
I got a compression tester. On my 50cc 2-stroke scooter, it was only 2 bar. Before I started troubleshooting, I went to the petrol 4-stroke lawnmower and tested it there, too. Also 2 bar. Now I'm wondering if I'm doing something wrong (although you can't really do anything wrong). The lawnmower runs well, and so…
