My Toyota service department says they’ve noticed that over time gasoline from Costco tends to cause more wear on engines because it doesn’t have additives like techron or techroline found in some brands of gasoline like Chevron, Texaco or Mobil. Does this make sense?

You’re being fed a line of BS by the dealer. No doubt a service writer was the one telling you this.

ROTFL So they have a forensics team there do they? Busy at work all day long dismantling engines and scrutinizing them for wear? And customers busy at work recording where each tank of gas is purchased?

Costco gas is fine. Was the guy telling you this wearing his tin foil hat? I wonder what other tripe he’s been feeding customers.

In fact, Costco’s gas contains 5 times the detergent level that is required by The EPA, so the allegation is baseless–and bizarre.

So you think every tankwagon that pulls up to the loading rack gets a different additive package depending on where the load is going to be delivered?? That’s almost comical…That’s not how the wholesale gasoline market works… If you think Shell gasoline has a completely different, proprietary, sec…

Back in the 1950s, there was always an ongoing argument as to which brand of gasoline was the best. My dad bought gasoline at an independent station that also sold groceries, but did no mechanical work. The proprietor told horror stories about people whose engines were damaged when they used a gas…

Sorry caddyman, but “splash blending” of additives is standard procedure at most loading racks, and not just for proprietary additives. Adding of ethanol depending on final destination may be done as well. Fuel distribution is a complicated affair requiring cooperation between competitors. An “Assoc…

“An “Associated” tanker may drive to the BP terminal to get a load to deliver to the Shell station, but the final outcome is that the fuel at a Chevron station is not the same fuel at a Shell or at Costco.” Yes it is…

No, it doesn’t. Costco would not sell any gasoline that is of inferior quality and set themselves up for lawsuits. Most gasoline is distributed by local refineries, whatever that might be. I have been using Costco gasoline for a long time, not exclusively-but enough to have noticed any potential downside.
