Cons of Using a CVT Another common complaint is that a CVT tends to make a vehicle drone loudly during acceleration. That's because it often forces the engine to run at high, constant rpm as the vehicle gets up to speed.

You will gain higher boost round mid revs so like 3-5 x1000. Also with all of that there should be a solid gain of 15-25 hp. When life passes you by, downshift.

No, there is no more harm done to the car while driving in ECO mode versus driving in “Regular” mode. ECO mode on most modern cars does a couple of things to help increase fuel economy: The transmission shifts at a lower engine RPM. The shifts may also take slightly longer.

Well, no. If you rev your engine in neutral, then drop the gear lever into D while the engine is revved high, you aren't going to go fast—you're going to violently and catastrophically break important stuff, and at best limp away from the line and coast to a stop, beaten and embarrassed.

Under normal driving conditions, this means changing up if the rev counter reaches between 2500-3000rpm. Under hard acceleration, you will change up a gear when you feel the acceleration drop away, which is usually above 6000rpm in a petrol-powered engine, but less if it's diesel-powered.

In the end, leaving your car idle for 30 seconds to a minute can do it no harm. Technically, letting it run idle longer will not cause much harm, either. However, keep other aspects of doing so in mind. Letting the engine run for no reason is a hazard to the environment.

While we prefer the latter, some times the simplicity of changing the way you drive and maintain your car can help. Engine knocking is nothing to ignore. ... Run your car for very long with this kind of problem, and it can cause serious engine damage.

If the engine appears to function normally, as before, it is likely OK to drive it. However, if the engine starts to misfire (you would see a flashing check engine light) then it is NOT OK to drive it all without risk of damage.

No. Driving with low oil pressure or low oil in the system can ruin the vehicle's engine, completely breaking the motor. If you notice the oil light on while you are driving or while the car is running, you should stop driving and have this problem addressed as soon as possible.

You can drive in 1st without more damage to the transmission. You should keep the engine speed to around 3,000 rpm or less which is close to the normal operating speed of the motor. ... As long as you are careful with it, you should be fine, just keep the RPM's down.

It takes 5 to 15 minutes for your engine to warm up while driving, so take it nice and easy for the first part of your drive. Performance cars often enforce that process with a graduated rev limiter—you don't get full RPM until the engine is up to temperature.

Assuming a properly tuned system, proper oil change and engine maintenance, and similar driving, supercharging generally will not shorten the life of an engine, just as is the case with OEM turbocharging (with proper cooldown for turbochargers. A cooldown period after driving is not necessary with supercharging).

Idling puts some level of wear on the ending, but as long as your oil is good and the engine isn't prone to overheating when air isn't flowing over the radiator, you're OK. Police spend practically all day idling their cars.
