Oil Smell

[Bud Fox]

I just switched from 15w-40 to semi synthetic Valvoline 2000 15w-40 . And ever since then I get a smell in the engine compartment after I stop and shut it off (kinda smells like gear oil a little). My question is does semi synthetic have a little odor to it or does it sound like something else?? No leaks under the hood at all and I never changed rear fluid since new with about 35K on truck now(havent checked level either) THANKS IN ADVANCE

Rednut, for a while now, engine oil's have had a strange strong odor.

This is probibally it, if you cant find a leak. It'll go away in about 500 miles, more or less.

Switch to Amsoil full synthetic . No smell ever and its by far the superior oil. Been using it for 40,000 miles. The Diesel loves this stuff.
