Monday night 8pm took me 30mins to dump oil change filter and oil on the Perkins M60hp. Approx 50 hrs since last change. unfortantly the Perkins hour taco has been faulty since purchase of Icon apparently it's some plastic cogs that fail. But logs indicate I change the oil every 50 hours I'm happy with that but I don't change the oil in the car! ??

Interesting topic.
Manufacturers manuals will say a certain number of hours or months whichever is first.
I often believe there conditions are often unrealistic or not practical for many with little issue with regular monitoring.
What do others believe?
Obviously different environments need to be considered.

I feel it's a bit like washing your car it always seems to drive better after a good scrub (something I don't do much these days) but changing black oil to clean oil defently I hear a diffrence in the sound of the diesel I'm not so sure on the filters but for $8 for a Perkins 409 filter might as well do the full job.. Runs sweet now.

A Perkins M60 sounds like a four-cylinder. If an engine of that size was in my tractor, and had regular use (even fortnightly) and inspection, I would change at 200 hours - no time limit. And nowadays I would closely follow the manufacturers oil spec's.

I could get 200 hours but prefer 50 to 60 hrs I think that was the manufacturer soecs. I like to see clean oil when I dip.

If you want to learn about engine servicing and use some products that will be very good for your engine go here ---> costeffective.com.au/

BTW, engine lubricating oil is designed to get dirty. Cleaning the engine is part of it's function. If it does not get dirty you should worry.

On H.M.A.S. Stalwart we ran the engine oil through Alfa Laval seperators (just like milk seperators) and though the oil was black as tar, it would test cleaner than brand new oil.

If you drive a motor vehicle for 100 hours at 100 klms/hour it travels 10,000 klms which is the maximum service interval recommended for most vehicles. Therefore running a marine engine at cruising speed for 100 hours is equivalent.

However many people change the engine oil in their motor vehicles every 5,000 klms, particularly if it is a high performance or heavy duty engine, which is fine. If though the engine does not rack up 100 hours running in six months, that period of time becomes the default service period as the oil will degrade and become acidic over time.

It is recommended that prior to draining engine oil that the engine be run up to normal operating temperature and then immediately dumped carrying most of the impurities with it. Dumping hot oil in the cramped space on a yacht can be problematic. Be careful you do not scorch yourself.

The most important thing with oil is it's quality i.e. stability and film strength. I only use Penrite, Bimrose or Caltex oils. www.bimrose.com.au/

I have heard some horror stories about Mobil oils especially if mixed with other brands.

Cheers.

That's why I use Vaaalvoline.

Nice to see an engine bay with rubber hoses and no plastic. Like the outboard fuel bulb for bleeding too.
On my fishing vessel, I used to change the oil and filters every 200 hours which was once a fortnight. That was a lot of oil! On my yacht, I change the oil and filters twice a year. I sail once a week all year round and run the engine at least 30 minutes each time I sail and that is not many hours. Most yachts do very few hours and the engines rarely wear out. Most of the damage is from internal corrosion I believe.

What is why you use Valvoline?

On H.M.A.S Latrobe, they used a 4 inch hemp hawser that was fed into a 44 gal drum of used oil.
It was run in a 6 inch steel pipe that went up two decks then goose necked back down to another drum fitted next to the original.
The oil moved up, over then down by capillary action and filled the drum with clean reusable oil.
The impurities were left in the hemp along the journey.
Of course this was during the Second World War and there were virtually no supplies of new oil in Australia , so they had to make do.
Dad told me that story.

gary

oil cleans the engine as well as lubricant the dirty oil needs to be replaced once its blackish. I work commercial charter, all engines get oil changed at 20 to 30 hrs and the boss says he knows when the oil needs a change just by the black oil and smell without looking at the electronic engine hr display!

Oil in my engine is just over a year since changing and 26 hours running and it's still reasonably clear.
Should I change it?

Yes.
Just the oil and leave the filter if you like and just change that every second oil change.

I think Penrite uses Mobil as a base oil

That may be so but it does not mean that Penrite Oil from say Repco is the same as Mobil oil from a servo.

There are only a few oil refineries in Australia from whom oil can be bought at different specifications.

As I understand it Bimrose specifies that the oil they buy must be ceramic filtered four times rather than just the standard one time. When they get it of course different elements are added to produce different grades of oil.

I have used Bimrose All Seasons oil in a number of vehicles and they have all run better as a result. You have to look around to find a Bimrose Distributor whereas Penrite is sold in most auto accessory shops.

A friend of mine works in a truck and machinery service shop and tells me there is a prime mover they service using Penrite exclusively and he also tells me that engine has driven for over 7 million kilometers without a rebuild.

As the ex owner of a clapped out Bukh who's oil would turn black immediately to the now owner of a brand new
Beta who's oil is still clean after 12 months, I'm convinced that it's what gets past the rings that affects the oil.

How often do your diesel fuel filters get replaced?
Is it common practice to use additives to disperse water and algae? I do and never had an issue over 15 years with same boat.

Interesting that they have only one supplier listed in NSW, at Moree and most of the other distributors don't sound like automotive businesses.

^^^ I assume you are referring to Bimrose. They supply a lot of oil to farmers.

.

Most modern diesel oils contain detergent. The detergent aids in cleaning the motor and helps suspend particles and stops them to sticking to hot areas in the engine. They help stop rings gumming, bore glazing and blockages..Detergent in the oil will eventually break down and regular oil changes are good to maintain the benefit. Non detergent oils are generally used in small petrol engines and two stroke,,, and they are still used in some diesel motors without concern. Non detergent oils are usually clearer (like sewing machine oil ) because they don't contain the additives but if used in a engine, the engine will discolour and get oil dirty just as quick as a detergent oil. If the oil is relatively clean in your engine the motor has good health. I have never seen oil drained from the sump that is as clean as the day it was put into service,,, But I have seen oil get filthy in no time due to being the wrong type.

The bloke who runs Atlantic oil was on TV the other day talking about their top of the line diesel used in long haul trucks. 50,000 miles between changes! Long haul trucks have their engines running for long periods at a time, exactly the opposite of what we do with our yacht engines. Stick with the cheap oils that the engine manufacturer recommends {grade} and change regularly. I buy whatever is cheap at Autopro/supercheap.

Yeah, I used to but I found that oil pressure dropped noticeably when the engine warmed, now I use shell rimula and pressure is maintained very well.

Oil pressure is another interesting consideration.
When cold looks ok then drops a bit which is normal .
However what is too low, if some pressure some good must be occurring?

.

Centrifugal separators are put into service for large quantities of oil cleaning.
They usually are on a bypass circuit that continually cycles the sump so that they are not restricted by the oil operating pressure of the motor.
They generally remove large particles in the oil that would normally clog filters. Nowadays Detergent oils ar more filter friendly.
The smallest centrifugal separator I have seen is on the end of the crankshaft of the old Honda XR 75
You also would see them on older trucks,, usually in combination multiple dunny roll filter unit.
Older style engines,,, before the introduction of detergents would sometimes have sediment catching pools incorporated into the castings that would require cleaning at specific service intervals

Oil pressure falling of when the engine is hot is often a symptom of worn crankshaft bearings,, Big ends may start knocking if pressure falls away too much

What oil pressure is too low?
I can not recall what mine is but much the same for the last 15 years.

I probably wouldn't want to see oil pressure below 10 psi at idle and below 50 psi at full rpm
Some engines are splash lubricated,,, others have pressure feed lubrication with complicated hydraulics that rely on oil pressure so it gets back to the type of engine,, with the manufacturers specifications.

Checked oil pressure today and 55 to 60 psi cruising and minimum 15 psi at idle when running at 83 c deg.
