What HDEO choices do I have in Midwest US for a SAE Viscosity 10W-40 that is an API CI/CJ4 specification. Trying to meet the Manual Requirements for a 10W-40 that I typically do not see available. It is a small IDI diesel tractor with 3 cylinder 1.1 liter. The Owner Manual is as follows: above 77 F (25C) SAE Viscosity 30w / 10W-30 / 10W-40 32 F to 77 F (0C to 25C) SAE Viscosity 20w / 10W-30 / 10W-40 below 32 F (0C) SAE Viscosity 10w / 10W-30 / 10W-40 I use the tractor spring/summer/fall with outside temperature range from 40F to 100F. I am not real comfortable using 10W-30 as is allowed in the manual and would like to use the 10W-40 if I can find it. Would like to use 15W-40 but that is not shown as a recommended oil. I am surprised that they do not allow a 15W-40 for temperatures above 32F. Thus that is why I am looking for a easy to locate 10W-40 CI/CJ4 oil. Thanks Slick

daman I must have missed the WM (looked this week)Shell T5 in 10W-40. CJ-4 would be fine. I will take another look. Thanks Slick

CATERHAM If I can not find the 10W-40 I either use 15W-40 or step up to the 5W-40 as not real happy using a 10W-30 above 90F when working the tractor hard
 
Ive never seen a rotella 10w-40 at WM. Id either make a blend of 5w-40 and 15w-40, or personally would just run syn 5w-40 and be done.

would'nt it be better to blend a 5W-30 with the 15W-40 ? if not, why not ? and what ratio is recommended to blend when using the 5W-30 and 15W-40 to achieve an oil that's lighter at startup yet heavier at operating temp's ?
 
Slick - you're in the midwest so it's likely that you have a farm supply nearby. Should be able to find a 10w-40 around you. That is the only place I've seen 10w-40 HDEOs. The T5 in 10w-30 and the T6 in 5w-40 have the same cold crank rating from shell; you're not going to see any benefit from the full syn in that regard. I will say that your fear of 10w-30 at higher temps is unwarranted. I've run my convetional Rotella 10w-30 in some really demanding environments, and had nothing but exellent performance in my Kubota tractor and my Duramax with the UOAs to show it more than capable. You can find the T5 10w-30 at nearly every WM. Also, many farm supply stores have this as well. My local Rural King has 10w-30 semi-syn in Mystik as well, and it's very cost effective. And Deere dealers have dino 10w-30 available; I've seen some really excellent UOAs from that product at well. I'm sure both the 10w-30 an 10w-40 will both do a great job, but I think you'll find it much easier to find the 10w-30, and for a better price, and it will perform every bit as well as the thicker grade.

I've not seen the 10w40 T5 at Wal-marts around here either, just the 10w30. I did however spot it at Tractor Supply Co. The T6 5w40 would be a good option as well.
 
Mystik Oil makes a CI4/SL 10w40 Syn Blen HDEO. I use it in a few of my Chevy small blocks in the summer with good results. Around here it is 22 bucks for a 2 gallon jug. See if you have a Mystik distributor around you or check with the farm stores.
 
dnewton3 and all Yes the 10W-30 HDEO fear is unwarranted. I even use it in my air cooled gas Lawn equipment calling for 10W-30 S_ rated oils. I use the T5 10W-30 silver jug Shell. So this oil is setting the barn now. Guess I need to just change with time and pour it in the diesel tractor as well. Even the tractor Owner Manual shows it as ok. Like you said it is available at most places My fear comes from excellent results using conventional 15W-40 and synthetic blend 5W-40 in the past with diesels. Always have used these for my Duramax, other diesel tractors, and Diesel Generator. So I safely think that my diesel must have a 40 on the right side of the multi-visocity numbers. Thus from the manufacturers callout of a 10W-30 and 10W-40 I wanted the 10W-40. Thanks

Don't fear the 10w-30, I am using it in several different diesels with good results. 10w-40 isn't nearly as readily available as it was 20 years ago, mainly because 20 years ago it didn't hold up very well. Tractor Supply stocks the Rotella version, but since your owners manual gives you a few choices you don't have the need to search. As far as the 10w-30 there are many choices available, as dnewton already suggested, syn, syn blend, and dino. For my different applications the Deere Plus 50 II (dino) seems to hold up quite well.
 
Slick - your maintenance plan should drive your lube choice. If your OCIs are going to be "normal" (in line with OEM guidelines) there is zero need for a synthetic; that in mind, use a conventional HDEO and all your equipment will be fine. If you're going to extend your OCIs, then synthetics (and bypass filtration) are great tools to utilize. Many brands to choose from should you take that route. You already stated that you have the T5 in 10w-30 in your barn; why not try it and run some UOAs to confirm the choice is a good one?

If you can get it, Petro-Canada has one, if not a couple, of 10W-40 HDEO's. Check their site.

Also, since this is a tractor engine, it may encounter diesel fuel with more sulfur than highway use diesel fuel, so finding a CI-4 approved oil could be a big advantage.
