What gives it the gummi bear smell?

Just wondering as I've never really noticed this myself when I've sniffed GC. However, tonight I opened a jug of XD-3 (0w30) and it smelled like liquid gummi. Is it the PAO that does it?

It may have something to do with the type and the high content of the Calcium used. Other oils with a lot of Ca can have the sweet smell.

[Off Topic!] I recently bought some Manitou Prep-M grease(made in USA by Motorex Switzerland) for my mountain bike fork, & it smells exactly like green GC......weird.

Something is wrong with your nose because my Esso XD-3 0w30 does not smell fruity or gummi like at all. It smells worse than regular dino oil. Castrol syntec does though, kinda like citrus.

I love this place! [Cheers!] Where else could one find the syntax celebrating scintillating Syntec smells. [Big Grin] Once I thought a fragrant rose Had subtly captivated my nose But then I realized that the effects Were coming from a bottle of SLX

[/QUOTE] That's odd. I just opened the other two jugs I have in the garage (0W30) and they both smell slightly sweet as well. If I had to describe it, the best I could say is that it smells slightly like a ripe mango. Maybe when my wife gets home from work I'll have her take a sniff and report back. Don't worry, she already thinks I'm strange. This will only reinforce that notion.

[LOL!] I am convinced they use an odorant that is an ester, but it is not the main complex ester used for FM and AW. I have in my lab some complex esters and they have little or no smell to them. But hey, those Gummie Bears have given their lives for less. [Roll Eyes]

I use a high quality Ca additive and it does have a slight but faint fruity odor. Now my wife thinks I'm a little weird as well. [Wink]
