Edgar, do yourself a favor and read on this forum after doing a search for this very issue. It has been covered many times. I must absolutely stress that this is a dry sump system and you cannot assume that if the oil is slightly below the bottom hole that that means 1 quart low. The oil has to be checked at 80°C plus or -10°C. The engineer recommends running the car at 2000 RPMs for 50 seconds and then shutting off the engine and checking the oil within one minute of the engine being shut off. The oil needs to be between the two dots. It is NOT linear below the two dots, meaning this type of oil dipstick needs to be checked multiple times to make sure that the oil is between those dots. Fill a little bit at a time and recheck a little bit at a time and recheck a little bit at a time and recheck until the oil is in between the dots.
Also note that these cars are designed to burn approximately 1 quart of oil per 650 miles, or 1 L per thousand kilometers. This is normal. This also requires you to check multiple times, regularly. frankly, in my opinion, this is the Achilles heel of the pre-LP cars — it is very easy to overfill the oil resulting in hydro lock and a blown engine.
