how can i tell if there is diesel in the oil?

why do you ask?

please fill out a signature with model, make, mods, etc...

Take a sample and get it analyzed, rubbing your fingers together with oil on them and then doing it with fresh oil will give you a lubricity guide.

just here talk about bad injectors which I think mine are bad. just curious on how to tell. who analysis oil samples do you know

Odor and keep your eye on the dipstick--you may have a problem if the level goes up!

If you suspect any luricant related issues, the first thing is to get a Used Oil Analysis (UOA).

Many services available. Blackstone Labs, Oil Analyzers, etc.

After you get it, please post up your results in the "maintenance and fluids" section, and not here. MOD

You can also do a quick paper towel test, not 100% fool-proof but... Basically just pull the dipstick and let a drop of oil fall on a paper towel. If you get a “halo” effect around the black oil dot you've got fuel in the oil.
