Miket, not sure what got you going, but here's some more factoids. There are actually two versions of the V10, both still in production. The original was 20 valves, approx 300 HP. It was famous for spitting out spark plugs and breaking exhaust valve studs. Both very expensive repairs. The newer engine has 30 valves (3/cyl) delivers 360 HP. It is fitted with a modified oil filter which extends down further 3" inches lower than original with the filter attached. I've owned both engines and the 1st was the 2 valve version. 1st oil change same issue, dipstick showed low level. I counted 6 cans and called Ford. They instructed 6 quarts only. The dipstick was riveted with zero markings except two hash marks.
6 quarts for the less HP 2 valve and 7 quarts, for the larger HP unit with cooler and larger oil pan.
They are not interchangeable and 18% over fill is begging for trouble. Replacement engines run 3500 -6000, not covered by ins or warranty. Rengineering is modification of factory specs. I also have a Cummins engine only its 8.9 liter, 450 HP
Attached is a chart by Ford showing uses of truck engines the class C uses the 20 valve engine, the class A uses the 30 valve engine. Therefore the Sunseeker in post 1 should be the 6 quart refill, not 6.5 or 7.
The 6.8 L (6760 cc, 413 CID) V10 is another variation of the Modular family created for use in large trucks. Bore size is 90.2 mm (3.552 in) and stroke is 105.8 mm (4.165 in), identical to the 5.4 L V8. Both 2-valve and 3-valve versions are currently produced. The 6.8 L uses a split-pin crank with 72° firing intervals and a balance shaft to quell vibrations inherent to a 90° bank angle V10 engine. The engine's firing order is 1-6-5-10-2-7-3-8-4-9. The 2-valve version was first introduced in 1997, with a 3-valve non-VCT version to follow in 2005. The 3-valve engines were built alongside the 2-valve engines at Ford's Windsor, Ontario LVL engine line, but moved production to the larger Windsor Engine Plant in 2009.
Vehicles equipped with the 6.8 L V10 Modular engine include the following:
