I'm trying to find out what stations use MMT in Canada, specifically Vancouver BC. so I can avoid those stations. MMT is a Manganese additive that my owners manual says to avoid. I found this link to Top Tier Stations that are supposedly not using it, but I would like to know which stations to avoid. (I tried to post the link but it's not letting me I don't know why.

Methylcyclopentadienyl manganese tricarbonyl (MMT or MCMT) is an organomanganese compound with the formula (CH3C5H4)Mn(CO)3. Marketed as a supplement to the gasoline additive tetraethyl lead to increase a fuel's octane rating, MMT was later used in unleaded gasoline. Following the implementation of the Clean Air Act (United States) (CAA) in 1970, MMT continued to be used alongside TEL in the US during the phase-out of leaded gasoline (prior to TEL being finally banned from US gasoline in 1995) and was also used in unleaded gasoline until 1977. Ethyl Corporation obtained a waiver from EPA in 1995. The waiver allows the use of MMT in US unleaded gasoline (not including reformulated gasoline) at a treat rate equivalent to 8.3 mg Mn/l.[1]

MMT has been used in Canadian gasoline since 1976 at a concentration up to 18 mg Mn/l (though the importation and interprovincial trade of gasoline containing MMT was restricted briefly during the period 1997-1998)[2][3] and was introduced into Australia in 2000. It is sold under the tradename HiTECĀ® 3000.[4] It was also marketed as Ecotane by T2 Labs.[5]

Not to pile on top of oilpan4...

But oilpan4 might have thought/confused MMT and MTBE which was used as an Oxygenate but was largely discontinued/limited as concerns over Ground Water Contamination was raised. Although to be fair... Gasoline ain't exactly Water Friendly either.

RFG - Reformulated Gasoline, blended to burn more cleanly. It reduces the pollutants that form smog and the toxicity of the air we breathe.
RFG was mandated by Congress in the 1990 Clean Air Act amendments. The first phase of the program began in 1995 and the second, and current, phase beegan in 2000.

RFG is required in US cities with high smog levels and is optional elsewhere.

ah, no oilpanan, MMT is still used in the US. As in Canada, the only fuels guaranteed to have no MMT or other metallics are the top tier fuels. It is currently manufactured for the US market by the Afton Chemical Corporation and the EPA allows the use of MMT in US unleaded gasoline at a treat rate equivalent to 8.3 mg Mn/l.
RFG apparently doesn't contain MMT, about 30% of the gasoline sold in the US is reformulated, according to the EPA.

I am pretty sure the U.S. went away from MMT about the time we went to RFG.
If I remember right MMT is a pretty nasty ground water contaminant and that was one of the reasons for going away from it.

Thomas Midgley, Jr. should figure in here somewhere.

Thank you for the information, very informative. Do you know what the standing is with the Canadian government now? Curious if anything has changed.

MMT is approved for use in both Canada and the US, and now Australia as well.
Known top tier gasoline brands in Canada are Esso, Chevron, Petro-Can, and Shell.
Yes, one of the requirements to meet top tier standards, and keep the certification, is to have no metallic additives.
Just because a station isn't branded one of the above 4, doesn't mean it is supplied with fuel containing MMT.
