Exxon adds a marker to verify the additive package is right - and a local store owner told me they grabbed a random sample. I’d think Shell does something similar …I'm fairly confident it does and would be surprised if it didn't. Would be pretty ****ing for their flagship product and overall brand image if it didn't.
What I'd really like to see is an 87 and 93 octane detergent comparison across brands (ExxonMobil, 76, Gulf, Chevron, Shell, bp, P66, Conoco, Sinclair, Sunoco, QT) repeated multiple times.
