LOL! That was just prior or maybe just into the beginning of my BITOG days, so I thought the engine would surely destroy itself if I didn't use that exact viscosity range and change it at a 3 month, 3000 mile interval. At the time I used to buy my oil at the local Advance Auto or Autozone who did carry 5w20.So being hard to find curious minds would like to know what did you really use or did you just take it to the dealer or oil store?
All those Crown Vic and Escape taxicabs with zillions of miles! And I don't think many were running on "syn" let alone boutique stuff.Put the 20 grade oil in a decent engine and it will run forever.

Thanks mate, good to see the original documentsHopefully these posted correctly...if not will re-post from computer later. Basically Ford and Honda requested 20 grade oils to help with mpg ratings - to help comply with CAFE.

Most of the higher mileage 4.6 need new valve stem seals,clears up the problems most times.All the ones I see smoke. Worn rings/stuck rings?

Our Crown Vic almost has 400,000 miles
To be fair, a 5W-20 SJ-SP has to be a blend...All those Crown Vic and Escape taxicabs with zillions of miles! And I don't think many were running on "syn" let alone boutique stuff.

It has been posted here before but CAFE has been around since 1975. My 75 LTD only get 10 miles per gallon. But it was the first year for catalytic converters to
