DP-G Oil

Yes, there will be at least two comments, depends which one you want to listen to :D

Actually I want to edit my reply. Is that oil synthetic? Can't tell as its in a funny lingo. As much as I am happy to use non-branded oil. I would only use synthetic, if that is what is required.

Turns out the 2nd link is actually the same oil as in my OP, just a different bottle... d'oh!

Anyhow, from the website: MANNOL Maxpower 4x4 SAE 75W-140 is a high-quality, fully synthetic gear oil for use in the differentials, including limited slip differential, for which highly sophisticated transmission fluids ("Limited SlipÖl API GL5") have been prescribed. It ensures a high protection against wear. It is used in particular in transmissions of sport and all-wheel vehicles.
 
Alt, don't take this personally but I am rather concerned about your approach to boat maintenance! You don't want a fuel filter that separates water because you don't have water in your fuel. And you don't want to buy genuine VP leg oil for the same reason. All I can say is that nobody has water in their fuel or in their leg UNTIL they find they have water present (it's not a matter of "if", it's a matter of "when")!

For me, decent fuel filters and decent leg oil are a price worth paying.
 
I think it’s ( VP,s gearoil for drives / IPS ) different as it’s described in the brochure I linked ^^^ .
I,ll explain why .
If you are big enough you can go back to suppliers and negotiate better terms ,not just price but you can asked them to modify the product , fine tune it to your needs , you can bolt on exclusivity agreements if you wish .
Works both ways contractually too ,you agree to min volumes .
If you are huge for them they will absorb development costs .Or you send your own guys in to advise them .
Either way the product is “ unique “ it’s not repacked plain vanilla .

It’s in Vp,s own interest in terns of user acceptance/ reliability/ confidence— regarding the gangly bits immersed in water to mitigate against the inevitable —- namely effects of water intrusion from where ever from a leak .

As said they are relaxed re the engine oil - happy to advise the spec and “approve “ others that arn,t in a blue packaging.
As with most engine manufacturers.
How ever with the dangly bits I ask you this , with gear oil ,can you see Volvo Penta approved anywhere ??

What you use is obviously your choise , but the point of order I,am saying is VP gear oil is not the same as cheaper stuff .
So racing to the bottom with the price is not comparing like for like .

There’s trading standards and such like in multiple markets , I drought very much they would make those claims in the link ^^ if they could not back them up —- particularly in the States .

pete - I am a Devil's Advocate, deal with it!

I have Racor FG500's on backorder from ASAP. Possibly the best (and most expensive) solution for my application. Also ordered spare filters and Loctite to ensure a good seal on the threads.

There is no need to be concerned, but thanks. I have been boating since I was approx. 9 years old and have owned my own boats since approx. 16 years old (granted i'm 30 now so not too long... bought my Cranchi Smeraldo when I was 25).

What I *am* doing is questioning everything. I am learning. Just because I ask questions, does not mean I follow through with ideas. I ask on these forums for advise (there's lots of it on here), rather than just go out and do it. My clients take the same approach almost daily with me. "I need X solution and there's a really cheap fix" - I advise them that it's cheap but won't work or won't last long. They take my advise and go with my advise. They ask, they learn... no harm done.

I am actually quite OCD about maintenance in general (for all my machinary). I keep a full log / receipts of everything and replace all usual service items (belts / filters / oils) annually regardless, and also bellows every 2 years regardless (i'm on fresh water, generally speaking less chance of bellows getting damaged as no barnacles etc) - if I showed you my receipt list, you'd change your mind.

For good measure, i'll take a pic of my engine bay for you the next day i'm down... the cleanliness will speak for itself.

No need, I recall seeing how mint your engine bay is, hence your original post seemed rather contradictory to your otherwise OCD ness!

As it stands, I think there's empirical evidence that the VP leg oil does contain some ingredient that means it retains some viscocity when contaminated with water. I know when we bought our boat, Col who checked the engines was very pleased to see that the leg was filled with the pukka stuff.

I appreciate that forums are very impersonal. If we were sitting at a bar and I asked the question, you'd know that it was a question of curiosity, rather than "I am doing this, I want opinions" :)

I take your point re. genuine stuff. I will see if it's possible to purchase in bulk (ie. 20 / 40 litre) VP stuff.

I didn't mention earlier, but I usually change my oil twice a year (Remember, OCD!) as I have a trailer for the boat (well, a launching trolley on steroids) so it's no big deal.... hence why I would be happy with non OE stuff.
(As a comparison, I change the oil in my car every 6k miles, but don't use oil from the Merc dealer!)

Guy that bought my Porto 35 , double checked that too , amongst everything else paper work wise .

So this OCD ness and history file contradict as the OP has a invoice for 3 yrs worth of plain vanilla gear oil - if I read post #1 correctly?

Also as well when it comes to sell , reflect how the DIY ness and lack of evidence for correct drive oil will look ?
Buyer will want a haircut or cheap price to cover the perceived risk .
 
It's a miserable, cold February evening, so here's some pics of the trolley :)

All entitled you our opinions. You've never seen the oil come out of my out-drives, but they've never been 'vanilla', or contaminated. I took a pic of the oil coming out last season (one of the oil changes it at end of season when boat comes out), it was clear!

Personally, i'd be much happier with a twice annual out-drive oil change, using a fully synthetic oil of the same spec, rather than annual (or in Ireland, i've seen worse) just because it had a VP label on it.

Same as a car... i'd be much happier to see a service record of regular oil changes, rather than a once-in-a-blue-moon oil change at a dealer using 'long life' oil.

(I appreciate this isin't a totally fair comparison)
 
Hope that airplane hanging up on the far wall has not got a camera mounted on it :cool::cool::eek:

Not sure where this is going? (plane isin't mine) But I hope not, sure I do be in the nip in the shed while working on the trailer :)

But where is this evidence?

The oil we use in our DPE which is non VP branded holds any water contamination in suspension just as well as the VP branded oil did that was in there when we bought the boat.

If VP were so insistent that their oil had "special additives" that other oils don't have then surely they wouldn't mind having this "special specification" written down somewhere.

You are kidding yourself thinking “plain vanilla “.bog standard automotive synthetic gear oil is the same
I moved away from outdrives , but I would not want anybody reading / enquiring about this subject to think it’s ok
to use some other stuff based on price - in some quasi belief it’s just the same stuff repacked.

Well we must have been "kidding ourselves" for the last ten years then with a sterndrive that according to some should have disintegrated many moons ago.

You been lucky, bet if you stripped down drive and checked wear then it might be another matter, if I were buying an boat with outdrive I would check what oil has been used and if anything other than genuine I would walk, and so would many others I have spoken to on the marina. That’s another reason to keep a good service history of all the right bits so not to give the impression that it’s been looked after on the cheap.

And that's your choice! I'm sure there are thousands of boats out there using high-quality non Volvo oil without issue.

I've had a LOT of out-drives in the past, didn't use Volvo oil and never had a problem.

I think that's because a lot of people don't understand and don't find out until it's too late

You have accused me of speaking on this subject without the appropriate knowledge to back it up. May I ask, where your expertise on this subject comes from?

Simply by reading the product information provided by the supplier. And of course by hearing people complaining about expensive outdrive repairs.

What about yourself ?
