Engine oil - can I use my tractor oil?

My recently acquired 1999 Td5 needs an oil change. The Haynes Manual calls for SAE 5W/40. Looking through the Morris Lubricants website they recommend their Multivis CST SS 10W/40.

I already have copious quantities of Massey Ferguson MF Power HC Plus 10W/40 in my shed which I'd ideally like to use to a) save money and b) reduce the number of part used barrels in the shed.

What real world problems might I have if I used this oil?

TIA

It's your motor, use what you like .....

Technically - No. 10W viscosity is too thick at lower tempertures for the TD5 engine. Nearly all modern engines use a 5W lower rating now, some even lower [0W]

The first figure is the cold viscosity rate, the last figure the hot viscosity rate, so the lower the first figure the better, the higher the last figure the better [within reason lol, 75/85W is a bit OTT]

Stick to a 5W/40 [ or even better a 0W/40]

Guns and Landrovers .... anything else is irrelevant.

Thanks Dave; I've gone for some Castrol EDGE Titanium FST Turbo Diesel 5W-40 instead

It won't harm the engine to use a 10w/40 instead of a 5w/40.
The main advantage l believe is fuel efficiency, a 5w/30 for instance will give lower friction loss in the engine and produce fractionally better MPG.
Unless you are planning a road trip to Alaska then the 10w/40 will be fine.

Just to say that I wouldn't trust the Morris Lubricants product selector. Despite them offering an engine oil that was BMW approved to the correct standard and grade, it recommended something entirely different for my BMW model. Very odd. 2007 110 TDCi Station Wagon XS

Mf hc plus or hc extra as it's now know is a 10/40 transmission oil with an additive package for wet brakes and clutch packs i wouldn't be using it in my td5, Mf 10/40 premium engine oil would be fine though. Ps all MF oils are supplied by morris lubricants
