WELL PUT!!!!!!!! Almost everyone already owns a wrench that will fit the drain plug, even if only an adjustable wrench.
The new cars have the dipstick tube, just no dipstick. There is a push on cap. A dipstick is available for service purposes but is VERY expensive.
I have been surprised at how I have been able to accept the no dipstick system. I can sit in the drivers seat and check the oil level with no rag or without lifting the hood. Since the engine uses no oil it works great for me.
There is still a drain plug, so changing the oil is no problem for me since I'm too poor to buy a "topsider."
Have a great day,
