Anybody have any experience or thoughts on this weight combination? We've been having temps in the -30C range over the last few days and the old dino juice is a wee bit too thick.

I think its a good idea to use a thinner viscosity, particularly in colder periods. I just dropped my oil pan and removed the bearing main bearing caps. The ones farthest from the oil pump (and therefore receive oil last when the engine is started) had the only noticeable wear. Also, the cam shaft had similar wear patterns. (107K miles on engine). Thicker oil takes longer to pump, and most of your wear occurs at startup. Personally, I would go with Mobil 1 10W-30. According to Mobil, it holds up like straight 40, so no worries. The tolerances on these engines aren't too tight, so 5W might be too thin.

Bill,

i use this oil in both rangie and disco. it doesn't get very cold in san diego, however, i used to hear valve tap in the disco after an overnight stay. now it's gone.

there's slightly more drip from the engine, but nowhere close to power steering leaks.

Geoff, 5W indicates that the oil behaves at absolute zero or thereabouts as a straight 5-weight oil would. [insert martha stewart slogan here]. in reality, the 5W50 oil never gets close to actually 5-weight oil at a room temperature, so it 5W50 is never too thin.

the 15/50 mobile is good stuff as well and it does great in the cold temps around here.

Bill,

I recently switched over to Castrol Syntec 5W-50 on my Disco. Temperatures in NJ have been getting as low as -20C and I noticed some hesitation in start-up with the factory fill. When I went in for the first maintenance, I asked the dealer to switch me over to synthetic.

The major difference I've noticed is that the car seems to start quicker and more readily on those extra cold mornings. The engine also seems to build revs more quickly compared to whatever LR puts in at the factory.

Haven't noticed any leaks yet. *knocks on wood*

oh and if your Discovery manual is the same as mine that is what is factory recommended for the most extreme temp ranges....

Thanks, everyone. Actually, I'm going to put this in a '93 RR with 125K kms. I used 10w-30 synthetic when I had my Disco and it worked fine, but I wasn't living in Northern Ontario at the time. I'm a bit clueless when the temps get below -20C in regard to lubricants. Seems like when it gets to -35C everything acts like it wants to snap off, drop off, or plain not move. Frankly, if this cold snap (if that's what you call it after 3 weeks) continues, I really don't want to hear much out of folks when it comes to "global warming". Right now, I'm all for any kind of warming.

Thanks again

0w30 in winter would be my choice if it gets that cold.

FWIW
