Help Tip: If you have a question that has not been answered to your satisfaction in the archives, it is always best to start a new thread of your own. By starting your own thread, you will receive the maximum number of views by forum members.

Below are some additional forum policies in hopes of all iboats members will follow, Thank you.

1. Please do not reply to old topics or hijack existing topics. Old topics of a technical nature are like a library book, Please do not write in them.

2. Old topics should be considered archives and used for reference only. Please do not reply to them.

3. Do not take over someone else’s topic (aka hijack) with your own question, even if it is similar. If you have a question that has not been covered to your satisfaction in the archives, it is always best to start a new topic of your own.

4. If you have a question for the original poster (OP) and the topic is over 30 days old, send the OP a PM, he may not even visit the forums any longer, or may not notice your question in the old topic.

5. By starting your own topic, you will receive the maximum number of views by forum helpers that may not even notice your question when it’s posted at the end of someone else’s topic. And those answers will be specific to your particular issue.

6. Please do not post to topics that have been inactive for more than 3 months unless you are the original poster. We have very active forums and any topic that remains inactive for that long should be considered "dead". It is especially confusing when there is an entirely new question posted to an old topic.

7. Posting at the end of any topic is considered to be hijacking the original posters topic which in turn subjects the topic to be closed if it continues to happen thus not making it fair to the original poster in the future had for some reason he/she needed to return for additional information or provide an update of the problem solved which is always welcomed within a reasonable amount of time frame.

8. Please note that you should see a red banner pop up near the bottom of each inactive topic asking you not to reply to old topics. The Red banner will read: Please note this topic has been inactive for 90 days. For the best results, please start a new topic.

Thank you all in advance for doing your part in helping iboats run a smooth ship.

  • Amsoil 10w30/SAE30 Diesel Engine Oil

    I'm new to the I/O world and searching for a replacement oil for sae30..... I know another oil thread sorry! couldn't find anything in the search.... was in contact with amsoil and they recommended their 10w-30/sae30 synthetic heavy duty diesel oil instead of their 10w-40 marine oil and said it was closer to the volvo penta new replacement for the SAE30. Has anyone used this oil before or does any recommend this or disaprove using?Or just use the factory 10w-40 volvo penta oil?
    thanks.

              I think were running 25w40 in our 305.

                While straight 30 was recommended at one time, that's not the only choice. You can use the Merc 25/40 that is available all over, or Shell Rotella/Chevron Delo 15/40. Some manuals also recommended 20/50. Just do not use a light viscosity car based oil like a 5/30 or 10/30, these have viscosity index improvers that can break down (not in syn, and not in the Merc oil) and the oil may not protect as well at high rpm use common with boats.

                  If the spec is the old 30w oil, it's likely an older engine and would prefer some mineral oil and not synthetic blends. A lot to be said for the lubrication properties of the good old mineral, in certain applications.
                  A good 15w-40 mineral will be just spot on.
