Really bad chemical/exhaust smell in cab after Oil change at Petro. Anybody had this problem?

Look for a plastic glove on EX. somewhere under turbo near oil filter?

 

Rotella has a different smell compare to Chevron Delo. Check your blow by hose/tube.

 

They probably spilled oil some place where it gets hot and maybe that's what your smelling. Check the exhaust.

 

Sorry ck. soon for a leak from oil filter thats getting on ex. somewhere, just find the wet spot on or near ex.

 

^^ That might be the answer . My current company uses Shell Rotella and when they spill the oil it smells like Kerosene until it all burns off..

 

Yep, check for a spill, or too much grease in a ujoint that got flung onto the DPF and is burning from the exhaust heat.

 

After I changed the oil in my truck I had a bad smell, too. But I took a shower n it went away.
