  1. I am with the channel owner. Use what the car maker prescribes for your car. Most cars will run just fine with any grade fuel, because for modern engines there are electronics to adjust the fuel injection for a wide range of fuel grades and operating conditions. With a higher grade fuel the engine will not gain more power, but a lower grade fuel may cost you a few hp which most of the time will not even be noticeable. There is a lot of fluffy marketing from car makers but they do not have any benefit by recommending a fuel grade that is not the best for an engine. - The superpremium - platinum - viagra100 fuels that are sold like champagne are propaganda only. There is no car in the market where the electronics are adjusted to this. - Avoid pumps that may have stale fuel, some Regular pumps are frequented very rarely!

  2. Combustion engines have useful torque only at certain rpm, which why we need a transmission. So while it is technically feasible, it is not practical to have combustion engine cars with no gears. Electric engines don't need gears, they have full torque at any rpm.

  5. VR6 will go forever. Avoid turbo if you like to keep a car for a long time.
