Where can i find a viscosity additive for chain saw bar oils?

You don't need this..just buy season appropriate oil for your chain oil, comes in light for winter, medium for spring and fall, and heavy for summer.Where can i find a viscosity additive for chain saw bar oils?
Take a look in your local phone book and look in the Yellow pages for equipment rentals. You should see a sub category for equipment maintenance. Most rental places as well as home improvement stores wil carry that additive.

Using two different viscosity motor oils

Is it alright to use 4 quarts of 5w-30 and 1 quart of 5w-20 oil in my car? The car is a 2004 Subaru Legacy and the oil is Castrol Syntec Blend. The car only takes 4.7 quarts of oil, so really I'd only be using .7 quarts of the 5w-20. Using two different viscosity motor oils
there will be no problems mixing the oilUsing two different viscosity motor oils
I would switch to full synthetic, but there should be no problem.

Mixing Motor Oil Viscosities?

My car needs an oil change badly. Most of its motor oil has evaporated from sitting there for two months (I know how bad that is for Delco Batteries).


The problem is that I need to move it 67 miles away from its current location because we moved. I know it will make the trip. When I get there I plan to do a complete oil change.


I have two quarts of 5W-30 and one quart of 5W-20. Will it be safe to mix those two? The ride is only once, as soon as I get there I will change the oil and filter as I have the supplies there.


Can anyone help!? Please and Thanks!Mixing Motor Oil Viscosities?
Oil does not evaporate, you either have a leak or the car burns oil. Yes oil is safe to mix, you end up with a viscosity somewhere between the two you are mixing.Mixing Motor Oil Viscosities?
Motor oil inside a engine does not evaporate, it all leaked out.


Yes you can mix those two oil weights.

Can old oil, or mixing oil viscosities have the same effect as no oil on an engine? (throwing a rod bearing)?

I bought an old mbz 190d diesel- The oil looked like it was suposed to- black. yesterday, the temp got a little higher than normal, but not overheating. I also notices a new click noise, faint. It leaks some oil, so I topped it off with 10w40. I don't know what was currently in there.


It began making the clicking knocking noise louder while running, and within 15 miles stalled and I believe it is near siezing.


I imagine that I threw a rod bearing or did some kind of severe internal engine damage. I'm trying to figure what the culprit was. old bad oil with viscosity breakdown? mixing oil types, or was this just to little too late. The car had over 400k miles on it.


thanks

any kind of oil,is better than no oil,ur motor may have ran out of oil before,and caused ur,bottom end damage.Can old oil, or mixing oil viscosities have the same effect as no oil on an engine? (throwing a rod bearing)?
I'm sure it was on it's way out and adding the oil was coincidental to it's timely demise.
That's alot of miles, but not for a diesal . I don't know if you know that a diesal takes a difforent motor oil then cars do. if you put the wrong oil in it that was the problem.
400K miles is alot, even for a diesel that size. Mixing viscosities wont hurt it at all, and neither will adding fresh oil to old oil. Your engine just worn out, bit the dust.
I don't think that mixing the oil had anything to do with it.

Why do auto manufacturers recomend using diff.viscosities of engine oil in cold and hot climates?

Thinner oil is easier to start in extreme cold temperatures. It flows to parts quicker. A multi-grade oil will start off low and get thicker as it warms up.

How is the right viscosity achieved in motor oils?

A general answer is that oil is a long chain hydrocarbon. When the oil comes up out of the well it can have a lot of different properties depending on the geology of the site. The oil has to be processed to make kerosene, gasoline, motor oil and other substances. The chemical plants that do this are complicated, and the process takes a long time.





If the chemical engineer wants a certain type of motor oil this is done through refining and distilling the petroleum. One of the most interesting parts of this process is called ';cracking'; the long chain of hydrocarbons so that it burns faster and cleaner. The whole process involves a lot of mathematics and computers. As far as industrial processes go, refining petroleum is one of the most complicated tasks.
