How many quirts of oil for the 80

[nmostofi]

just did an oil change, the manual states that the truck uses 7.3L I put 8 liters in there (mobile1 synthetic) but my gage is still showing below two thirds, anyone know how much oil does the truck take ?

When I do a drain and fill and change the oil filter mine takes about 8.5 quarts to get it to the full line.

I have been using oil by the gallon in the 80, I have about a quart left over of the second gallon so should be ~7qt’s, but I am using the small 20004 Toyota filter, but the other filter should only be about a 1/2 quart more?


7 quart [US, liquid] = 6.6244707 liter

Just re-read that, first I though you meant dip stick, but now might be oil pressure gage? If so that my be normal depending on you definition of "two thirds"

Oil pressure only changes with quantity when you don’t have enough oil,

Normal oil pressure will change with temperature, viscosity, and RPM,

Higher RPM = higher pressure until relief pressure it hit, same with lower temperature and higher viscosity

Thanks Raven, I was referring the gage, it changes as the truck gets in motion, when the truck is stopped it drops down the quarter but as the truck is driven it raises to two thirds. I believe this is normal, as far as the dipstick it shows "full".

If my memory serves the manual states 7.9 w/o filter and 8.5 with filter.

The gauge is an OIL PRESSURE gauge, NOT AN OIL LEVEL GAUGE. Check the oil level with the dipstick. If the oil pressure guage ever goes down to nothing while you are driving, pull over and do not drive further, even if the dipstick says there is enough oil.

Well even thou that's your oil pressure guage, I'd say that's pretty nice pressure if you're using 10w-30.

FWIW, I have to use 15w-40 to get the same results.
