5W-30
That's the factory recommendation for that engine size. And Castrol High Mileage works really great for me in my 1981 Ford F-150 with a 4.9L inline six.
1992 ford f150 straight six cylinder
I don't know if it's the same as the (1996 ) Ford F-150 straight six but that is ( 6 quarts with engine oil filter change )
Motorcraft FL-1-A engine oil filter ( for the 300 straight six , 302 and 351 V8 )
I don't know if the 1995 is the same as the ( 1996 ) Ford F-150 but the 4.9 liter straight six takes ( 6 quarts with engine oil filter change )
The 1996 F150 owners manual shows SAE 5 W - 30 for the 5.8 L ( and SAE 10 W - 30 for the 4.9 L straight six and the 5.0 L V8 )
On a 1993 Ford F-150 : The 4.9 litre / 300 cubic inch inline six cylinder doesn't have a timing chain It has a large gear on the end of the camshaft that meshes with a small gear on the end of the crankshaft
six u.s. quarts;however,only with a new oil filter.
Don't mess with that adjustment. The idle speed is electronically controlled.
1 - 5 - 3 - 6 - 2 - 4 ( distributor rotates CLOCKWISE )
Your 4.9 L - straight six cylinder is 300 cubic inches , if that's what you are asking ?
use 5 quarts.
Four cylinder needs five quarts, six cylinder needs six quarts.
