There's a recent thread on that here: Caterpillar 3116/3126 engine oil availability

I have always used the CAT SAEO oil, but as mentioned in the above thread, that's no longer available for our use. I was at the local CAT dealer yesterday hoping to buy their DEO-ULS 15w-40 oil, but they had none in stock and couldn't tell me when they would get any in. Since I'm doing my oil change this weekend, I found a local NAPA that will have the Rotella T1 30w in stock tomorrow, so I'm going with that this round.

Mine are 1998 3116s. Others on this forum have been using the T1 straight weight oil for years with no problems, I was only using the SAEO in the past because of my previous concerns with sooting, but those have been addressed and the latest oils have been proven to be safe to run in our engines.

I think you will be fine. The 40w is appropriate (I think) for Florida, I went with 30w since I operate in a colder environment and tend to use the boat year round, so I need the lighter weight (higher viscosity) formula.

You are 100% good to go with Rotella T1. 40 wt would be preferred, but 30 would be OK if that’s all you can find.

I found it at Advance Auto Parts at $20 gallon. You’ll need 15 gallons.

if you have a Westerbeke genny, you can use 30 Wt in it. That’s what I do FWIW.

Thanks!

I agree with everything above but location is sometimes a factor so adding that to your profile would help with advise now and in the future.
