Never Change Your Oil Again !!

[deerefan]

I'm not so sure this belongs in the Brooklyn Bridge category. There are a fair number of trucks, trawlers, remote generators etc that use this system and seem to do fine. I'd imagine that the lubricity of a modern synthetic oil would greatly outlast the typical oil change interval used today even if it didn't last a million miles. With oil analysis readily available it seems you could pretty easily monitor the situation and change the oil as needed rather than on a relatively arbitrary schedule. I have no idea what the system costs but it would certainly cut down on oil use and oil disposal costs. For a remote generator where you'd need to send a technician out to change the oil and perhaps require a backup generator while you did so it might make sense. Same for a trawler out at sea for a few weeks where it could easily run up over 500 hours of continuous engine use and where shutting down the engine to change the oil presents any number of problems. It does seem a bit bulky for use in a CUT but for big rigs, boats and generators it might make a lot of sense. Love to see an independent scientific/engineering review of the topic.

Don't get me wrong, I bet it works and may work well. In some situations, it is probably better. But for normal cars and trucks use in normal day to day conditions and for people on tight budgets, I would not take a chance having to rebuild an engine prematurely because I strayed from a tried and true method. I wish I had something to try it out on, maybe an older less valuable truck or tractor.

If I had a vehicle that used a qt every 1000 miles I would never change the oil. Just add and keep going. I'd do the filter every 15000 miles but that would be it.

I remember about 3 years ago reading an article where a guy took his new Camaro and used it for oil tests. He tested Mobil 1, Amsoil, and several others. He drained a little oil and sent it to Blackstone labs every 3,000 miles. Many of the oils were good to 20,000 miles and longer. The funny thing was that his adding 1/4 qt to replace the drained oil was having an impact.

Oil does not break down or wear out, That's not what I've heard

this is what we call marketing.

because if everyone knew our product would last 10x longer than we said, then we would sell 10x less of it and thats not good for the shareholders.

ask eddie how important it is to keep your engine oil CLEAN no matter what the age of it is. ie a good filter is 100x better than just changing the oil. am i saying you dont need to go without changeing the oil.... probibly not

i run 10-15K miles on an oil and filter change. but im very paticular about my filters.

I run Amsoil in my 07 Dodge Cummins and have almost 20,000 miles on the oil and filter and its been good so far. I will continue to use Amsoil in my truck.Amsoil makes a by-pass kit for Dodge, Chevy and Ford diesels and I know a lot of people that use them and just do the anlasis. Later... Bullsram

Thanks, But no thanks.

guess I am just old fashioned, I just sleep better knowing I changed the oil and filter.

Interesting..think I'll........ "bypass" tho.

I wouldn't use it on a tractor that gets only 100-200hrs use a year and can be easily serviced. For very high use engines in situations where maintenance is an ordeal though I'd certainly consider it.

I don't understand that statement at all. The petroleum products probably don't wear out, but the additives do, and contaminants that mix in with the oil, may change some of the chemistry, and put your system in jeopardy. What do you think the purpose is for an oil analysis?

If one could clean the oil, remove unwanted contaminants such as water, acids, etc, and add the necessary components to use the product in the system, for which it was designed, then that would be a good thing.

Yes, you can add new oil, but you are adding it to a crankcase of old sludge, to be mixed on the first engine start.

Worn out oil certainly changes viscosity and after using "Re-claimed" oil in heavy equipment it certainly appears to have a shorter life ....We do oil tests on things like rear ends in CAT D8 dozers to extend the life of oil because it's $500 for oil and filters but fail to see the need to test motor oil from a 4cyl that can be serviced for $70..???
I've removed the crankcases of far too many 10'000hr tractors and seen very few with any sludge or deposits stuck in there...They are designed to drain...It's penny pinching just change it..?

Not something to be proud of but lol...we have a 89 GM truck with 490'000 that is the "farm truck" with the compressor ,generator ,welder and is the moving toolbox but still on the road.
The old 350 knocks like a beast and bluesmokes and probably used a liter of oil a week and was deemed not worth repairing 8 years ago so gets topped up with 15/40 most of the time .."Stopped it smoking" and it keeps going and going...?
