Here's what I got: 1989 Cadillac Brougham d'Elegance 5.0 V8 4BBL Engine (307 CID) with 19,800 actual miles. Genuine GM Service Information Manual says to put in 5 & 1/2 quarts 5W-30 oil with new filter during oil change. Did this twice since I purchased the car last year. I let the car run a bit to warm the engine then drop the oil plug & filter & remove oil filler cap. Let drain for 1/2 hour or so, while I clean up the oil that dripped on my glasses and ran down my to arm pits. Put some fresh oil in the new filter before installing and the rest down the filler tube, for a total of 5 1/2 quarts. Due to the clarity of the new oil and length of the dip stick along with the awkward curves of the dip stick tube I am unable to get a good oil level reading on the stick until after about a week of driving or until the oil begins to turn brownish in color. ANYWAY when all said and done, the dip stick consistently shows about half inch above full mark when checked first thing in the morning before running the engine. Is this OKAY or am I putting in too much oil? Also, will this damage the engine?
