Motor Oil

[demeanor]

What type of motor oil should I use for a 1996 5.0 Ford Volvo Penta with Fuel Injection? Also what type of oil filter? I used to be a Mercruiser owner and I am new to Volvo Penta.

Re: Motor Oil

it strikes me that any good quality automotive 20/50 mutigrade oil will keep these old gm engines happy in all climates.. all the rest that gets said is nit-picking confusing waffle and should only matter to a scientist..<br /><br />trog100

Re: Motor Oil

I would guess that for most boaters that run less than 50 hours a year, change there oil each year during winterization, and don't run at WOT all the time, any grade oil, even the cheapest on the shelves will work. It's those few that must run WOT for hours on end, day after day, that really see the effect of the better oils.

Re: Motor Oil

i wouldnt dare mention the word "cheap" on here don.. but i think u are entirely right.. its only those who push the limits that need to be worrying overly much about what oil goes in their engines.. i will lower my comment to average as opposed to good quality.. errrr.. even praps cheap.. he he<br /><br />20/50 is just a good all rounder for older style engines..<br /><br />trog100

Well, in case you haven't noticed, I'm not afraid to speak my piece around here. And, I agree with you, which doesn't happen that often. <br /><br />Kind of makes you wonder why the 2 leading drive manufactures (Mercruiser and Volvo) both specify 20/50 for their GM and Ford (in Volvo's case) engines. They test oil constantly to find the best oil for the marine enviornment for the engines, maybe they should just listen to all the oil experts that frequent this site.

Re: Motor Oil

I have always used Q.S. straight 40 weight in all of my boats and never had an issue related, course average temp in the summertime here is 123 degrees (at the lake).

Sounds like something I would have said, come to think about it I think I have said something to that effect before. <br /><br />I believe your right about being able to run what ya brung so to speak, I also believe that what is going to set the new F-WC oils apart are the storage properties more than anything as most of todays modern oils are going to meet all the anti foaming and fuel delution problems head on. If your boat has a minimum time out of the water, say three months or less, I see no real reason not to use what ya want, but if it sets in a moist environment for longer than that, you need to use a F-WC oil or a good diesel oil, or one of the High mileage oils. Personally I would use Dello 400 15W-40 or a 20W-50 High Mileage oil.<br /><br />He, He, we are having fun now.

Re: Motor Oil

years ago in the UK we used to have a summer grade oil and a winter grade oil for our cars.. there aint a deal of difference tween our winters and summer anyways.. but we used to use a different weight oil depending on the season..<br /><br />summer was a straight 30 i think and winter was a straight 20.. 30 in winter was considered to cause to much cold start load on the poor old battery.. and 20 in summer was considered to get too thin when hot..<br /><br />then along came some dudes with an oil called Duckams 20/50.. a bright green colour it was.. they first advertized it for lowering oil consumption on worn engines and of course such multigrade oils soon put an end to the age old practise of having summer and winter oil.. the same as a 20 when cold and the same as a 50 when hot.. jeesh how wonderfull.. the general idea back then was the thicker an oil stayed when hot the better and the thinner it was when cold the better..<br /><br />the other interesting thing is that when 20/50 went (or was driven) out of fashion and thinner oils like 15/40 or 10/30 became the norm.. the advertizing push behind em wasnt about thinner oil being better for your engine cos back then everyone knew (had been told) it wasnt.. he he.. it was about the new thinner stuff causing less drag and saving fuel.. your engine might not last as long with this new thinner oil but the saving in fuel consumption over its life would outweigh by a mile its slightly shorter lifespan.. it all made a basic kinda sense with fuel prices rocketing as they did in the UK back then..<br /><br />course beliefs change and folks somehow have gotten to believe that thinner oil is better for their engine.. i still have my doubts and pay more attention to how thick it stays when its hot rather than how thin it is when its cold.. he he he..<br /><br />take this straight 30 engine oil thing.. now 20/50 is thinner when its cold than 30..(good) and thicker when its hot than 30..(good).. why on earth would anybody choose to use a straight 30 oil which seems inferior in every respect to the good old 20/50.. i know its a boat.. but even boats must follow some logic.. he he <br /><br />one for lubedude this.. imagine a straight common or garden 30 weight oil say.. lets use 0c as cold and 100c as hot.. now we all know that the oil is thicker at 0c than it is at 100c but by how much.. or to put it another way how much does none multigrade oil thin out as it gets hot.. lets use 0 to 100 centigrade.. freezing to water boiling kinda temps..<br /><br />trog100

Re: Motor Oil

Well Trog:<br /><br />Being a SAE30, It is suppose to be a SAE30 when cold and a SAE30 when hot as far as protection goes, But have you ever seen how thin a SAE30 comes out of an engine when hot. It looks like water. How it looks has little to do with how it will protect though they tell us.<br /><br />When the new 5W-20 oils came out, I was pretty sceptical, but it appears that they are holding up well (In the vehicles that are requiring them), with very good wear #s. Most are a semi synthetic but not all.<br /><br />A 20W-50 I would think would be a very good oil for a boat due to the 20W (The "W" stands for winter) for starting and the 50 for when running WOT. Ive always wondered at what temp the oil would come into the 50 weight catagory. Running at around 140 degrees may not be enough. If you are going to run a 20W-50 though, I would use one of the new High Mileage oils as they have a much better add pack and would come the closest to making the new F-WC designation.

Re: Motor Oil

yep i am too old.. he he.. old enough to have seen common beliefs come and go.. old enough to not put too much faith in "todays" common beliefs cos i know given a few years they will all be turned upside down and reversed.. he he..<br /><br />i recon it happens every twenty years or so on average.. what was ceases to be.. and new set of rules comes in.. <br /><br />i still dont trust oil that gets as thin as cat-**** when its hot.. he he..<br /><br />and oil under WOT load as it goes thru the big-end bearing probably gets far hotter than the 140 degrees the coolant temp gauge reads.. depending on the engine load of course..<br /><br />and whilst i can easily see the benefts of a 5/20 when the engine is cold i cant somehow fathom the benifits of cat-**** oil when hot.. except praps for improved gas mileage due to the less drag factor.. this logic also fits in with boat engines being about the only things left on the planet that have good old fashioned 20/50 reccomended for em.. with boats gas mileage dont matter as much as good engine protection..<br /><br />i recon cat-**** oil is all about fuel economy cos thats the thing that gets top priority according to todays set of rules..<br /><br />i read lots about "todays" engines needing and benefiting from thinner oils but very little as to why or how they do.. so far i have never come across anything thats changed my old fashioned theory about the thicker an oil stays when its hot the better.. he he<br /><br />just me being "old" fashioned.. 60 at my next birthday by the way.. he he..<br /><br />trog100<br /><br />ps.. lubedude.. "Ive always wondered at what temp the oil would come into the 50 weight catagory"..<br /><br />i think the lower figure is supposed to be what straight oil a multigrade would be the equivant of at 0 degrees celsius and the higher figure is what straight oil the multigrade would be the equivalent of at 100 degrees celsius.. thats how i have always understood it..

I have a way of looking at owners manuals maybe a bit differently that most. When I see something like that, I see it as a <br /> "Recomendation" rather than "You can only use this or that. Sometimes it even says "Recomended oil".<br /><br />This is where I get my rear in the ringer so to speak with people like TheOilDoc, I dont necesarily follow the book. I mean no dissrespect, he knows his stuff, Im just a bit of a rebel. <br /><br />So, with that said, I would think that a 15W40 Diesel oil would be a better choice. Dello 400 if it were me, but still change it out every season.
