Doesn't the trace materials listed in uoa's end up on your rings and cylinder walls after burning? Precipitate?

Users of used cooking oil for biodeisel are getting their raw product for free now, may even get paid to pick it up. If serious money is being made off bio it won't be free for long. Big investments will be made in technology that can make and kept in big pockets. Hydrogen generators fit that...

A deisel/electric hybrid will get alot of attention around this forum then.

I read in this forum that Walmart labels some bypass filters for non-bypass applications. I can see why they do this as they can order larger amounts to be manufactured at once to save a few pennies per filter, but how is this accepted if a warranty is called on?

LPG=liquified petrolium gas=the way it is shipped in cean tankers. CNG=compressed natural gas=as used in vehicles dispensed from equipment hooked to gas utilities lines. PPG=butane=as despensed from trucks to customer's storage tanks. JP4, JP8, jet fuel=kerosene=was cheap when used for...

[QB] And I thought that a filter with a bypass valve in it was a bypass filter and that a fullflow filter had no bypass and all the oil had to go thru the filter so the full flow has to go thru the filter.

Only a certain percentage of the holes in the filter is the stated size. The one that was linked stated a rangre of 4 microns to 24 microns for one media type. Must be why they use the multi-pass rating. Around 1978 I ran across a salesman with aluminum spin on shell that held rolls of toilet...

When you know you got the best, You don't mind people knowing who's not as good.

What would be in the 60 to 100 hp range?

Yeah, why ask questions when you can just take some Materials Engineering courses at the Southern Houston Institute of Technology?

Gary, Since it is a bypass filter it will go into by-pass mode if the oil pressure is greater than 8-12psi on the high side. That would mean that the spring restrictor would have to open with less pressure than the by-pass of the bypass filter. Does that mean that the bypass filter has a...

Is there such a thing? Small and lite diesel engines? I remember the 3 cyl. supercharged one in the 1970's Gamma Goat. But it wasn't so lite.

Do you think that all the crap that is lodged in your filter is going to pop out if the filter goes into bypass? No! If your oil has enough floaties in it to worry about them settling onto the bypass valve end and then being washed into your engine you got problems.

No, I assume that I have a full filter and oil channels that has an open end drop to the oil pan. I also think that the back pressure of the oil distribution depends on enough oil going thru the filter or bypass to build pressure against the open-ended distribution paths. I agree that this is...
