Is there any difference between Regular oil and Marine oil??? If so, what is it? Will is harm the motor if you use regular oil?

No, it won't harm your engine if you use regular oil. Just make sure it is of reasonable quality and the right weight. A marine engine gets hard use.

The 15W-40 that is required in our Indmar engine is the same spec as 15W-40 diesel engine oil.

Your manual will have a two letter spec: SD, SJ, etc. Match that up with your oil purchase and you are good to go. I use a bulk synthetic made for diesel engines and it works great; and is much less expensive than by the quart.

Just purchased Cheveron Delo 400 (15w 40) from Sams Club today, I paid $55.00 for 6 one gallon jugs. If you buy just 5 quarts of oil at your local auto parts store it will cost you almost $30.00, just my 2-Cents.
