I use Castrol saf-xo. Was cheap from dealer and it's OE.

but.... not all dealers are created equal and/or use BMW/OEM lubes... around here we use whatever we can get (and that we trust)!

Finding an alternative that actually even mentions the OEM spec is a good start...

We're considering a newer X3 for daily use, which would free up our 2004 (E53) X5 4.4i as a weekend tow vehicle (replacing a string of Jeep SUVs from 4.0L, 5.2L and 5.9L, mainly for the beefier trans more than displacement, as the race trailers gained weight over the years). Duties will include hauling a 10K gross trailer with WD hitch at speed for up to half days non-stop at a time, from about -10F to +112F. I've already grabbed the heavier pre-facelift OEM hitch, although the facelift version's holding so far. For drivetrain lubes, I'm either already using or moving to:


N62 4.4L engine: 10W-30 full synthetic


Rear diff: 75-140 full synthetic


Front diff: 75-90 full synthetic


ZF Auto 6-spd: ATF+4 full synthetic (since BMW/Lifeguard6 is apparently just Mercon SP dino oil)


X-Drive transfer case: Need further advice (understood NOT ATF, but is the stock BMW fluid full synthetic or is there anything better?)


I don't want to make this a brand discussion, but any comments on proposed fluid specs greatly appreciated! It has the factory trans fluid cooler. Is that likely sufficient, or should I go bigger? Any other coolers needed for summer towing? Thanks in advance!

What's your trailer weigh fully loaded? You know the V8s were rated either 5,500 or 6,000lbs towing capacity, right?



I tow a camper that weighs about 4,000lbs fully loaded throughout the summers in up to about 105F, and it handles it just fine with a WD hitch. We typically have the AC blasting in the summer heat while climbing 8% grades and recently got two SUPs to put on top of the car too. Sometimes I will be at WOT in 3rd or 4th for 15 minutes straight without lifting in order to get over a pass. This is my third summer doing this routine and I've never had any sort of failure.



I use some sort of synthetic oil, usually 5w40 or 10w40, with Valvoline full synthetic diff oil and trans fluid. I don't know what the N62 oil spec is but I would err on the side of heavier oil instead of thinner, since your oil will generally be hotter when towing than normal operation.



I do not have an auto or a V8, but that's my experience and it's worth exactly what you paid for it.

The type of lubricant is part of the design criteria of driveline components. I use only the recommended OE lubricant for transmission, diffs and the transfer case for that reason. Better lubricants are not necessarily better for a component. Engine oil is an exception and I don't want to get into that either. As far as engine oil, any good brand with same specs and weight changed frequently will be fine.

I would be as or more concerned with the suspension, tires and brakes.. I would refresh the suspension and go to heavy duty shocks and struts if you haven't already. Tires? I don't do any towing with my X5 so don't know what is out there but I would want them on wider rims than stock. I would go to bigger brakes.

That said, I think you are asking for trouble using your X5 in the conditions you mentioned. You need a vehicle that is built with towing in mind which would include in the conditions you mention. Otherwise, my guess is you will be very late for some of your destinations.
