My Mercury Grand Marquis has 150,000 miles on it. My OCI is 5000 miles using MC 5w20 mostly and MC filter.
For the last 50,000 miles or so I started having to top off a quart every 3000 miles or so.
Is there any other type of oil like the higher mileage oils that will either prevent or help this oil loss?
The cheap in me is saying if the higher mileage oil is $20 per 5 qts, and I pay $15 for MC, the $5 in difference I use to put back into the car when I top off.
What do you think?
TIA
