fwebster provide me with some infor on the 3116 & 3126 that I felt should be moved from the 'Westerbeke Diesel Gen Set' to this fourm.
It has been discussed before but many like issues can be tuff to track sometimes.
Here is the message that has just been posted:

Caterpillar's website isn't the friendliest one out there simply because there is too much on it.
The problem with multiviscosity oils is that Cat has found that the viscosity enhancers in the oil will b reak down and adhere to the inside of the aftercoolers and restrict air flow. They don't even recommend using their own oil....DEO. Cat has developed a synthetic oil for just the 3116 and 3126 because these are the only 2 engine types to have the problem. The Cat synthetic is covered in their publication # PEHP9516. Almost no Cat dealer stocks it becvause of the cost.
As an alternative Cat recommends a sinvle viscosity SAE 30 or 40 depending upon your ambient temperatures. Look at page 16 and 17 in Cat Publication # SEBU6251-12,"Caterpillar Commercial Diesel Fluid Recommendations".
Go to www.cat.com and search for the pub. #'s........search box is in the upper right corner.
Frank,
Many thanks for the info. To make a long story short the publication # PEHP9516 does not have all the correct serial numbers that apply. I first found mine was not listed and thought it was fine with the 15-40 multi-grade oil. Upon reading the much larger (90 pages) in the Cat Publication # SEBU6251-12,"Caterpillar Commercial Diesel Fluid Recommendations" it became obvious the previous document had not been updated since 1999 which was its original publication date.
The current Publication # SEBU6251-12 has many more beginning specific serial numbers that apply which included my specific engines. This publication calls for either 30 or 40 weight depending on ambient temperatures the engines are used in. It would appear that mine would best be severed with 40 weight I believe but I am waiting on an email from Cat clarify which would be best for me to use.
It should be noted that I had Carter Cat tell me the 15-40 multi-grade oil was the correct oil for my engines which seems to be incorrect when further investigation is done. They also stated that my engines had all the updated preformed that now leave me a bit concerned so I will go through another path and try and double check the info on the updates.
The 90 page docuemnt is lock as well a can be read but not printed :huh: out so you will need to read as much info as you want but the serial numbers involved are referenced on page 16 of 90.
Again many thanks for your information :smt038, comments and directions for all of us whom enjoy CSR so much. It is a daily connection I make because of the info available from valuable resources.
