Diesel oil and zink

This is the oil i run in my boat. I have a 20.5 advantage with a chevy 454, stock motor as far as i know, 850 carb. i thought that it was a inmar motor but not positive. it has a inmar bell housing on it, however no inmar stamps on the oil pan. I was told by inmar west coat that on the oil pan is the only place to be sure if its one of there motors because the bell housing could have came from anything or any place. the kicker is it isnt the orginal motor. the orginal motor was a blown 540, but the orginal owners put a 454 in it before they sold it and kept there monster.

That said the guy at inmar west coast there the "jetpac" motors where built said to run 15w-40.

I like valvoline alot, and it isnt very expensive for this oil and being that it is certified to be in diesels it should be good oil. I understand that the little cummins approved decal on the bottle and a dollar wont get you a cup of coffee, these days. but it makes me feel good. i would also think that since this is diesel oil and not till the last few years they didnt run cats and since diesels run harsh and with a shit ton of compression, it would make sence to have high levels of zink, but what the hell do i know..

finally the big ?ion is big block chevy turnin 4700 WOT, doesnt burn oil at all, 50 psi oil preasure, does any one know if this oil has enough zink or the EDDP or what ever for my flat tappet cam.....

I like tring to take care of my stuff to the best of my ability and askin a question can somtimes help you from makin a big mistake.

The disel engine run close bearing tolerances, extreme combustion, extreme heat. The presure on top of the piston puts extreme presure on the rod bearings and run near top RPM all the time. A car or truck engines runs on the low RPM and don't run that severe pace all the time. So if the engine is built to run extreme pace his thinking why not run a oil made for severe runing.

They were really cool on the phone and very helpfull. Not sure what i am gonna do, i think i am just gonna keep runnin what i got going for the rest of the summer and make a change next year to VR1, i think it is 20-50. I know that we all knew that the VR1 had ZDDP however i wanted to confirm it and wanted to know how much. I also wanted to know about the diesel oil. I guess if it isnt considered racing oil there is no way in hell it is gonna have alot of cat killing ZDDP God bless America

I run the 20w50 VR1, thats what Dales Speed and Marine recommended. I've never had a problem.

I run 20-50 too the only problem I have is I get a little high on pressure.. I would no doubt start with 20-50.

I think you are on the right track. I run Rotella 15-40 in both of my boats and have never run into any problems.

X 2 on Rotella, also with a splash of Lucas Stabalizer

I've run Kendall 50wt in the past, and just switched to Amzoil 15/50wt dominator. Both work fine for me.

Personally, for a boat I see an advantage in using "diesel oil" vs a 'quality brand' race/off road oil...the off road/race oil will usually have a higher level of protection package.

Years back, diesel oil had a stout level of zinc...and other main additives that were specifically designed to 'suspend soot' in the oil so it could be captured by the filter.

Diesel FUEL ain't what it use to be either...now, very dry and the once beneficial lubrication property's of diesel fuel are lowered too. The once looooong lived diesel engine is a thing of the past. (Thank the EPA for that)

Lucas Stabilizer does nothing but 'thicken' the oil...if that's what you want > just use a thicker oil > but keeping in mind, super-thick oil doesn't make it's way back to the pan and oil PU as quick too.
If you want to beef-up the oils thickness AND have some added zinc protection I would use STP.
Or, simply purchase a bottle of Zinc > follow the manufactures dosage as too much ZDDP is just as bad as not having enough.

ok big hammer what do you think of my mixture of running the blue premimum and the ZDDPlus additive. i personally think i would have a winning combination with that
