OK, please tell me that I am wrong and misunderstood the US volume scales and conversion from quarts to liters (or give me a good address to a loan shark). ![Wink :wink: :wink:](https://www.steelsoldiers.com/images/smilies/icon_wink.gif)
Following the Lubrication Order, my 1973 M51A2 needs
- about 21 liters of oil for the engine itself
- about 28 liters of oil for the drive train (gearbox, transfer case, differentials etc)
- about 10.5 liters of oil for the steering
- about 35 liters of oil for the dump hydraulics
Using standard over the counter prices in the Netherlands this would set me back about 450 EUR not counting the dump hydraulics nor the fuel - and oil filters! Have to find a cheaper source.
Engine oil: most common used here is 15 W 40, but one guy from my garage recommended 20 W 50. The latter has specification exceeding Mil-L-46152 B/C. Any comments? Or do these engines need un-doped oils (not likely for a 1973 truck)?
Drive train: available here is 80W 90, API GL5 standard, exceeding Mil-L-2105 B and CCMC G2/D1 standards. Sounds ok?
Hydraulics. Bit at a loss here what the current useful European alternative is. Standard used here for heavy machinery is hydraulic oil according standard ISO VG 32 and DIN 51524, at about 15 Eur per liter. Not sure if you still can get the straight-grade 10 engine oil, if that is the equivalent of this OE/HDO 10.
Please advice what is the best deal for this truck. It has about 3 000 miles and less than 500 hours on the counter. Probably the last time anybody changed anything was in 1986. Top quality oil would be nice, but killing and probably unnecessary in this engine.
