Salt protection marine engine oil If we had salt contamination in the engine oil on the ships I sailed on I'd have probably lost my effing job.
The company I am familiar with, Shell, certainly doesn't list anti salt additivesor whatever you want to call them.
Have a look at their TDS's in this link - you won't find anything there.

Not bikes, but we had a customer who bought a fleet of Vauxhall Combo vans for their engineers.
The headline service interval was 20K, but nobody read the small print, which said under arduous conditions every 10K, where arduous was defined as lots of stop start driving, which inner London drivers are bound to do.
When they started coming in for first services at 20K, lots of them had hardly any oil in them (can't expect the drivers to check, it's not their van and most of them wouldn't have the brains to be able to open the bonnet) and what was there was in pretty poor condition.
This problem was exacerbated by the fact that they had a very small capacity, so if you burnt off a litre, you reduced your oil contents by a third.
We advised them to start doing oil changes every 10K, but it was too late, by 40k most of them had rattly timing chains and a few had snapped them, we must've done three dozen engine rebuilds on those. ____________________ Things get better with age; I'm close to being magnificent........

One of the jobs I have done as part of my career in lubricants was heading up the analytical laboratory that, amongst other things, investigated serious problems in which the oil was implicated. We always discovered that the cause of the failure was down to some other factor - misuse, misapplication, contamination etc. The oil held the evidence, but was never the cause. The right oil, used the right way, should see you right. As Shaft says though, you need to be clear on what "the right way" is, including any severe use and top-up requirements.
Max to min of a typical Eurobox car engine is usually around 1 litre. If you have 1 litre missing from a 5 litre oil charge, that's 20% of the oil gone. That leaves the remaining 4 litres to do the work that 5 litres could be doing. Hence my advice, when asked, is to keep an engine topped up to the max mark, rather than wait until it reaches min before adding a slug. Every top-up you do is like a shot in the arm for the oil, adding fresh additives and base oil as well as getting the level up. ____________________

Reminds me of my first programming gig...
One day I was wandering through the office - it's amazing how much work you can avoid if you socialise with co-workers - and one of the sales bods was lazing about.
Not out on the road?
"Nah , car's fucked."
Oh? What's up with it?
"Fucked if I know!"
Turns out the primary problem was lack of oil When I caught up with the sales guy later he got quite shirty! "Not my fucking job, do I look like a fucking mechanic?!"
I was pretty young but it was at that point in my life I resolved never to be "that guy" ____________________ Husqvarna Vitpilen 401, Yamaha XSR700, Honda Rebel, Yamaha DT175, Suzuki SV650 (loan) Fazer 600, Keeway Superlight 125, 50cc turd scooter |

Not engine oil but an interesting note.
We run a big spur gear by an electric motor on drilling equipment. The 'Top Drive' that turns the drill pipe with the bit on the end,
The most common major repair for top drives is gear bearing or spindle bearing failure.
We had two drives with catastrophic bearing failure after only 6 months drilling from brand new.
We replaced the bearings and some cnut suggested it was the bearing manufacturer was the problem.
I use bearing regularly and bearings do not really fail due to manufacturing reasons. Even the Chinesium ones.
There is almost always another reason.
Overloading. Running a bearing longer than it's lifetime, the wrong lube or no lube.
Common bearing failure is oil contamination.
In drilling we use mud a mixture of clay and oil or water as the solvent and some other chemicals in there to.
We sample every month and act on results.
We were getting bad samples showing clays in the gear oil.
We just drain refill with fresh until we can pull the drive out for shop repair. It takes about 10 days to swap the bearings and at US$70000/day it's a bull-buster for down time.
We sent oil for more stringent testing at Mobil and Castrol to get balanced report.
Both came back with the same advice.
Water in the oil was more than 2%
The oil manufacturer told us that 1% oil was the maximum they allowed before the oil loses it's properties.
The gear boxes hold about 50 litres. 1/2 litre of water killed the oil.
There were additional factors causing early bearing failure so a stack up of issues culminated in the crash.
It cost $millions to rectify. parts, specialists, downtime.
But illustrated to all the Luddites how important oil is for the life of the equipment.
Another bonus that came out of this was that we started using the multigrade gear oil we had in the warehouse that a couple of us moaned about using. It would work for summer and winter +50C - -50C.
They'd previously said 'it was too expensive'.
Not as expensive as a lube crash. ____________________ Disclaimer: The comments above may be predicted text and not necessarily the opinion of MCN. |
