Hello:
I have semi technical questions regarding the W203 that I recently purchase:

o This new model doesn't have an oil dipstick for the engine. I have to rely 100% on the computer to tell me if oil is needed or there is too much oil. The regular place where dipstick is usually located is simply a plastic plug. Is there an OEM dipstick for this model so that I can physically check how much oil is in the engine?

o This car has a 6 speed manual transmission unfortunately MB manual never mention about the recommended speed for shifting gears. Does anybody have a good recommendation so I can get the best mileage?( and I want to prevent lagging)

Thanks,

Jim
