What oil weight to run in my M119 in the deep south??

[Ascension]

Car had just had a change when I got it and has since new run Castrol GTX last change was 5-30.
I'm thinking 15-50 or 10-40 for this climate.
It will be synthetic but don't need a oil debate on different brands only a recommendation of a weight for this climate. Even with 5-30 never seen it hit 1 bar or lower even at the warmest at idle so she seems in good shape but 5-30 here?? Nope I have 10/40 in both the others and am leaning going there with the 420 but with the tendency of these M-119's to leak oil like a freekin old Harley am considering the 15/50.

There are at least a dozen oil related threads on this forum.

Here's my vote for your car if you want to use synthetic but are worried about leaks: I have had excellent luck with Mobil 1 "high mileage" 10W-40. I have used it because all of their published specifications for it as far as phosphorus levels etc. correspond perfectly with their MB229.3 and .5 approved oils, telling me that they are the same basic formulation. And they specifically mention a little extra seal swelling chemistry. And yes I have seen perfectly dry older engines switched to synthetics, including other Mobil1 formulations, that spilled more oil than Captain Hazelwood shortly after the change. I have used this "high mileage" 10-40 formulation in a number of my own and friends cars and have not seen leaks develop from it, so that's why am throwing my two cents in here on it. And I do think you should probably run a synthetic, if for no other reason than Dino with the requisite amount of zinc / phosphorus is hard for most people to find. That being said, I still would change it at least by 7.5 K miles. If I ran dino, I would absolutely go no more than five, and probably be closer to four K. miles.

IMO, people worry far too much about the weight on the low temperature end of the scale, at least when it comes to synthetics. You are never going to experience greater engine wear with a five or a zero cold weight multi viscosity synthetic, including some of the newer fakey-do synthetics like the Mobil1 based stuff that I just recommended up above. But thicker oil when it's cold does at least conceptually increase wear and fuel consumption until it's warmed up. Thick oil in a cold motor also runs at a higher pressure, which helps precisely nothing but does increase the chances of blowing out your oil tube plugs. You aren't racing at LeMans, or even Lemons, so as long as you're picking a synthetic, don't worry one whit about zero or five cold weights.

Like you, I am partial to seeing higher weights on the hot end of the spectrum even though I am certain that they offer no benefit whatsoever over a high temperature 30 weight synthetic to you and I driving these things on the street, even very aggressively.

Good call, Honcho! That particular oil thread actually didn't suck. I guess that's why you get the big bucks...

Mine ran in South Florida for a long time on 15w50, but it wasn't driven much before I bought it. I switched to 10w40 synthetic, just because it's easier to find and not that serious, the way I drive the car and how often it gets changed. It sees maybe 5k a year, mostly highway, and gets changed yearly.

Cheers,

Turns out my son is a big diesel guy and we were able to buy up a few gallons of ROTELLO T6 5-40 full synthetic for $15 a gallon. I think 8 quarts of that should handle the job pretty well with the MANN filter I have.
Know there have been the oil threads here but every one I saw went WAY out in the weeds on everything BUT the actual weight of the oil for a warmer climate so---.

Rotello ... must be Shell's Italian version of Rotella?

The thread I mentioned above had a fair amount of info about oils and hot climes. I too, live in what could be called the "deep South." I think Houston/Southeast Texas is probably deeper even than much if not MOST of Alabama.

Never used the stuff before and my son will be here tomorrow with a few gallons.
Yep that particular thread I had missed and was one of the few oil threads here that didn't totally turn into a circle jerk
