I noticed that some posters here have noticed some differences in the color and smells of oils. I recently bought some Chervon supreme and the stuff almost looks completely clear, it kind of suprised me, for another car of mine I bought some castrol GTX and noticed it was a lot darker, and on the back of the container of GTX it says that from time to time the color/smell of their oil will change due to enhancements. Are these color/smell differences in oils due to the additive packages? Any info would be helpful.

i have looked into that before and i agree differnt oils smell differnt and also put outo differnt emmisions. castrol is kinda a dark colored more smelling oil compared to penzioil with pure base which i sreally clear and burns clean. i think its just whwat is in the oil that they use to protect the engine. taking it a step further...differnt oils smell different when burned...like my mobil drive clean is kinda a dim smell of exaust but castrol was really smellin lik oil...i dont have any info to back my statement up though..only my nose..

Some time ago, back in July, we had an smelling contest.

The various smells mostly eminate from the additives. As stated in the thread, I have PAO, esters, and regular dinos in pure form, and none of them have a really distinct smell by themselves that I can discern.
