Rubber gloves for dirty work

Can anyone recommend gloves for dirty/greasy/oily work? I have never used, have no idea what to buy. I saw some 5 mil nitrile gloves but the box was too large, I didn't want to buy that many and don't even know what I need. Working with chainsaws, dirty chains and whatnot or for working on a tractor. Sometimes I just wish I would have had rubber gloves on, my nails get nasty, lol, and then it takes days for them to clean up.

 

I have tried pretty much all of them. These seem to hold up the best.

 

These are my second choice.

 

I generally use the same ones i have for all purpose work. Latex coated stretch gloves. I have a pair in the shop just for that purpose...when i work on saws.

 

These ones are great. Textured for some grip with slippery stuff.

 

I'm thinking that this guy doesn't have dirty fingernails.

 

Just slippery ones.

 

Those are the ones we use on medical calls at work. They seem to hold up well.

 

I use different ones depending on what I'm doing but my all time favorite are the 5 1/2 mil blue nitrile gloves from McMaster.
They offer up to 3XL and you can slip them on and off several times.
Rather impressive list of things that won't touch them.
Slightly pricey if you toss them every use.
