10w oil

[Kitz]

:confused2:hi everyone. i just got a 1982 ih 244 compact with 2000 hrs on k3d diesel. its dipping into the teens and my owners manual says to use 5w-20 or 5w-30 below 0 degrees. 10w oil below 32 degrees. and 30w above 32 degrees and not to substitute 10w-30 or 10w-40 i cant find 10w and id like to run syn oil. would anyone have any ideas on what i could use that would meet class cd oil and that i could use all winter season. thanks for any input.

Rotella also offers a semi-synthetic diesel oil in 10w-30. At my WalMart, but YMMV. Silver gallon jug.

By coincidence I called Caterpillar Tractor today because my 1975 model requires 30 wt or 10 wt depending on temperature and I was no longer finding it at my regular supplier

I was told I should be using Rotella 15-40 in my mild CA climate year-round

Your owners manual allows 5w30. You can get diesel rated oils in this multi-grade good for year round service. This is what is used in our VW TDIs, 2009+. I use Mobil 1 0w30 in my 4010. It has a mild diesel rating. I change it before 100 hours vs. rated for up to 200 hours by the manufacturer of the engine. TDIs go 10k miles on synthetic 5w30.

A 5w30 surpasses 10w, etc. requirements. Gives you down to 5w at startup and 30w at operating temperature.

Use Rotella is that's your wish but here is better choice IMO

Synthetic 5W-30 Heavy-Duty Diesel Oil

I second K7LN's recommendation. I use synthetic 5W-40 in EVERYTHING I own. One oil on shelf. Goes in push mower, riding mowers, pressure washer, generator, 1950 Ford 8N, wifes car, my truck, Kubota, etc. This is a mixed fleet oil for many year round all climate applications, 0F to 95F for me.

well it sounds like im going with rotella. its more accessable. well with 4 quarts 5w-40 syn would it be ok to fill the last quart with 15w-40 non syn. i used that in my mower and have a extra qt plus its twice as costy for a qt. amsoil is 10 dollars a qt here thats real costly but to each his own.

Can you add 1 quart of 15w-40 to 4 quarts 5w-40, yes. Would I do it, no. Would it hurt anything, no. Doing this dilutes the fine properties of synthetic oil you just used. Philip.

Go to your wal-mart and grab some T6 Rotella or Mobil 1 TDT both are 5w40's with great pour point specs and WILL perform fine and flow great in them cold temps and protect your engine beautifully.

Just buy 2 gallons of your rotella of choice. Pour 1 qt out of the second to complete your oil change. Set the other 3 on the shelf for either your mower or adding to that oil burner car you have or like me (i use regular rotella 15-40), i leave it on the shelf and next oil change i will buy a new gallon of rotella and then use anouther qt out of the partial jug. So it will be 4 oil changes till you will need to buy a second gallon again. Like you said a single qt is almost half of what the gallon costs. If buying 2 gallons will break you or cause financial strain you might rethink the whole tractor thing.

Yea i would not mix either. It will not hurt, thats what semi-syn oil is anyway. But you spent money to get the syn, why turn it into a semi-syn oil?
