Had my 20 hour service completed on a F150 Yamaha. The dealer used 7 qts of oil. I talked to him regarding the fact that the manual states essentially 5 qts are used. The manual also states the oil should registered 1/2 way between upper and lower markings on the dipstick. The dealer stated they usually put 7 qts in. Would 7 qts move the oil level up to the top of the markings? I’m concerned about overfilling the oil.
