diesel oil

[thebicman]

During the winter I have been using 10w30 diesel and have never had an issue. What I'm finding is that 10w30 is getting more difficult to find. Or am I missing something when it talks about oil class for my B2601. Manual states "not to use CJ-4" and a lot of the oils I've been looking at have a CJ-4 classification. Been using Castrol that has a CH-4 rating. Comments or thought on this.

CJ-4 is was not recommended for the new Tier engines - due to the chance it would damage the anti-pollution equipment. Thus it was a huge CYA for Kubota.

Then it appears they changed their tune.

read this ...which is FROM Kubota....

And for what it is worth.....I would NOT run a 10w30 oil in the climate you are working in

I would jump as fast as I could jump to a 5w-40 weight oil....which is very easy to obtain and your engine will be better lubricated....when your temps fall below zero - your engine will love you for it!

Personally I would get some Rotella T6 or better yet......Amsoil 5w-40,
dont let the price tag fool you - you can get it cheaper (then again the Canadian dollar might be much different)

Yep - Hokie nailed it.

I don't have a block heater. 5w is a dream on cold starts versus the 15w I was using. (I do have a battery tender, which is great in the winter)

I use Rotella T6, and have been considering a switch to Amsoil.

I’ve been running Rotella T6 5W-40. I managed to get 4 gallons of T6 for a net cost of $14 total after tax. I took advantage of Shell’s $7/gallon mail in rebate when Autozone was running a 2 gallon for $19.99 special a few weeks ago.

Many thanks for the advise. For sure 5w40 is easier to get and can even find it in a full synthetic. Price is very reasonable if on sale.

I use Valvoline 5W-40 Premium Blue Extreme Synthetic Diesel Engine Oil.

Menards is about the only place I find 10w30 Rotella

I took the advise of this forum and have now switched to 5w40 syn. So much easier to find.

The cost of oil is not an issue for me...my question is...is switching to full synthetic with the different weight oil (5w-40 for syn vs.15w-40) better for the engine over the long haul? I have been using T4 for years....if the switch is easier and better for the engine. Tractor is listed in my info...thanks
