The car is a 95 DeVille Concours

Today we had the third oil change since owning the car. Previously the shops used 7.5 quarts but today when I paid the invoice this shop said you owe for 9 quarts of oil. Surprised to say the least because I thought my Jag at 8 quarts was a thirsty thing.

When I got home I looked at previous invoices (1 from today's shop and 1 from another shop). The last time we were at today's shop, th invoice from that time said 6 quarts (hm?). The other previous shop said 7.5 quarts.

My Alldata account says that with new a new filter, it should take 7.5 quarts.

I would rather run a bit low than over fill the oil. The seals on this car are in very good shape (no oil drips) and I don't want the extra pressure of too much oil.

The question is this, does the Notrhstar engine take 7.5 or 9 quarts.

 

the frist shop sound close could be that the frsit shop did not change filler just oil wicth holds
about 1 qt.
second shop may be taking you for a ride.


but RTFM= read the f Manul
