I agree, anything less than full is lowThe Full mark is there for a reason. Keep the level there.
Depends for me. A couple weeks from an oil change? Nah. A couple thousand miles until oil change. I'll top it off.My dipstick looks like this with 5 holes drilled between ADD and FULL :
ADD| . . . . . |FULL
If the oil level is down to the 3rd hole, should I add some oil to bring it up to the FULL line?
One of my cars holds 4.5, but always put the 5 qts in.Both of my cars hold 4.2 quarts, so I always have left over oil to use.
