Anything wrong with running xd-3 0w30?

[allan5oh]

UOA's look fantastic running shell 15w40, but I want to go with a thinner synthetic.

xd-3 0w30 is 12 cst at 210F

I assume it will shear a bit, since esso is known to load up their synthetics with VII's.

Run in a 12 litre volvo diesel engine, semi truck.

I would use the XD3 0W40.

I'm with DRoc, BUT you could always try the 0w30 and send in a sample to see how everything is holding up.

Since you obviously use the vehicle to pull loads and work, I'm not sure I'd want a 12.0 cSt oil as the protecting layer in my engine.

If you do get shearing and if there are other factors at work (fuel dilution) then that 30 weight oil can be at a 20W or below before you know it. My :2cents:

XD3 0-30 has a visc rating at 100C of 12.2, you have option of XD3 0-40 with a visc rating at 15.7, thing is one fella in here had shear problems with a Ford 7.3 PSD (apparently oil shearing on all oils problematic for his engine) and he used the 0-40 XD3 and found it sheared big time, the 0-30 XD3 sheared very little in comparison in the same engine.

I use 0-40 Xd3 in my 12 litre Cummins, cold here too, 0-40 XD3 has the same -65F pour point as the 0-30 XD3, works great, not much more in cost for 0-40 if you want a little beefier syn oil.

Good luck,

Thanks for the responses. I ended up getting the 0w30.

I'll keep a close eye, and do very short UOA's. I'll keep you guys updated.

If all else fails, I could always go 50/50 with the two.

Cyprs, if that's true, then the 0w30 has much less VII's then the 0w40 correct?

So if the 0w40 shears down to 14, and the 0w30 stays at 12, I don't see a big difference do you?

My engine is very easy on oil.

In fairness to the 0-40 XD3, I use XD3 0-40 in winter for extreme cold use and on this 12 litre cap Cummins my oil shears from 15.7 to 14.8 in 6000kms OCI winter. I do use the 0-30 in my Gassers.

50/50 would be great, I have talked to Esso reps on mixing, mixing the syn HDEOs is fine, but he stress to stay in same brand, dont mix brands especially in syn oils, mixing XD3 15-40 dino with the XD3 syns is fine too,I have done it with great success on oil anylysis, full 100% clearance from Esso techs on mix XD3 in my research.

The fella name was something like Quadlube or the like, he had a shear monster PSD, on that particular engine he found the Oil sheared less with 0-30 XD3 than 0-40, that was one particular isolated case, I dont have shear problems with the 0-40 nor have I heard of any other problems to date in here on it. On my Cummins I sheared from 15.7 to 14.8 on a winter 6000Km OCI, not a problem for me.

Honestly ,I am not qualified to answer your VII's question so I wont, but if your engine is easy on oil then it is very similar to a cummins, you should have no problem in winter with a 0-30 in my opinion. I know an Esso rep who uses 0-30 in his new Cummins diesel in summer, it can get +100F here in my area, he does not have any concerns or problems, so 0-30 should be a safe bet in winter IMO, monitor like you say.

If you like syn XD3 then I would try 0-40 summer and winter.
In your harsh climate there, it may be more economical to use syn year round, in this country it is easy to find oneself with half an OCI left with thick 15-40 summer diesel in cold fall/early winter with cold starts, syn year round stops this waste of oil in dumping prematurely and forcing OCI schedules. Many farmers/ranchers here with numerous diesels go syn year round to combat this problem, there is only about $2.00 per litre dif from XD3 syn to XD3 dino, in our climate it can actually save money going syn year round in saving in uneccessary OCs.

Is it not the other way around?... with reference to shearing potential?

From what I understand, given the same oil, as it is in the case of XD-3 0Wxx's, the further the spread in grade the more likely the oil will shear, due to the fact that there are more viscosity improvers (in this case) in the 0W40 oil than the 0W30.

This would explain why the 0W30 tends to be more shear stable than the 0W40, would it not?

Also, Esso's site has a picture of all their HDEO's being poured from beakers at the same time at a temperature of (I believe) around minus 35. The 0W30 clearly flows better than the 0W40.

Factory recommendations for the temps you are running in are usually the best choice. The engines are kinda pricy to be experiment with.

That is what UOA's are for. They give you plenty of warning of engine damage.

Without UOA's one would have to be alot more careful deviating from factory recommendations.

Paul, I dont know if you are questioning my comments or not? I dont know if you misunderstand me or I you? I refused to answer the viscosity question because I was not qualified. In my reference to the fella with shear problems in is PSD as an example in my first post, I now believe his name was Quicklude, he tried XD3 0-40, big time shear. He then tried 0-30 XD3, it sheared less and his OCI ending visc on 0-30 was excellent, from my view point, I did make a point that the 0-30 in that case was more shear stable. Personally I have great success with both 0-40 and 0-30 XD3 in each of my particualar engine applications, neither oil shears drastically for me in my experience.

As far as the cold flow on the two great oils go, I missed the flow test Esso now shows, I based my comments on the past Esso Site spec sheet and my personal use of these oils. Both oils specify an ambient temp in the literature of -40F/C, and both oils state a -48C pour point rate.

I have started my Cummins in -25C with XD3 0-40 in parking lot without heat pad and blockheater, did amazingly great in pressuring up quick but I wont use 0-40 in my gassers in winter, 0-30 there always.

Cyprs, sorry, I wasn't questioning you in particular. I was just trying to get straight on the viscosity spread/shear potential ratio. Thanks for your comments, though.

 

[Cyprs]

Paul, no opology was needed, I was just concerned of a misunderstanding or if I was misinforming people.

I looked for the Esso site cold pour demostration, big site, could not find it, if yu could, please tell me where on the site to find it.

Many in here in past have related 0-30 XD3 to being close to a 40 weight in specs, 12.2 visc/100C in 30 weight. I sometimes wonder if 0-30 XD3 is too heavy for my 4 cylindered tight clearanced gas Nissan engines on extreme cold starts. Many other farmers in my area only stock XD3 15-40 for farm machinery and run it in EVERYTING (gas and diesel) on their site year round successfully, guess that gives me some comfort in using an HDEO 0-30 XD3 in winter.

thanks Paul,

Same experience. I talked to 2 different Esso techs and both gave the green light to mix XD-3 15W40 and 0W30.
