My Predator 4000 watt generator manual says the oil capacity is ".6 Quart (.6L)". Is the letter "L" for liter? If so there is a big difference. Which should I use?

Only specs I can find

You do not list the engine size. This truck comes with 3 engines. 5.4 V8, 7.3 Diesel, and a V10. Your owner's manual will list the capacity. The add mark normally means add 1 quart on a V8. Add 1/2 quart wait 5 minutes and check the level again. The 5.4 L V8 capacity is 6 quarts of 5w20 with filter change. If it is a diesel then it requires a special oil for diesels which is 15w40 weight and it holds 14.5 quarts.

LS1 4.8 5.3 6.0 takes around 6 liters with oil filter. put 5 liters then run for 60 secs let sit for 5 mins then top it up till it reads full on the dipstick .( DO NOT OVERFILL)

As for the sludge question, I add Marvel Mystery Oil around 600 miles before i do my oil change. This will clean out the oil pick up screen and oil journals through out the engine, I do this on every oil change and i have over 356,000 miles on my engine. Oil and filter changed every 3,000 miles intervals. Good luck and hope this helps.

It should be listed in the owners manual, but because of different oil cooler setups you may have to do the change yourself and add oil until the correct level is established..... for the first oil change.
Most likely 7 liters,but start with 5,run the engine to fill the oil filter,let it sit for 5 mins and recheck and fill to full.
Note the amount needed for next time.

With the filter this motor is right @ 4.5 quart. In practice most will put in the full 5 quarts with no issues. The extra .5 quart will not cause the crank to splash in the oil.
I hope the may have assisted,
Tom

look in the manual in dash it has all capacities in it, i have a 2007, it holds 6 quart with filter change, tell you what, change the oil and filter ,add 5 quarts if its a v-8 crank for a min, shut off let sit a while check dip stick to see if you are full or quart low, best thing to do if you cant find in manual, hope to help you ,robert b.

did you start the engine yet to see if the filter is full? The filter will hold about a qt.

5.6 liters here in the UK, could be a faulty sensor but try the oil first, easy enough to drain, jack up the rear passenger side so it gets all the oil out when draining.
