I spoke at length with one of their Reps about my urge to switch to one of their "Turbo" models. The fellow was very forthcoming and explained that unless I was prepared to pay for 93 octane on a full-time basis. the turbos are not worth the extra money. Mazda does agree that the cars will run on 87 octanes, naturally producing less hp but in the long run, you might run into premature fouling and turbo issues with the cheaper gas.
Absolutely false. I have no idea why a sales rep would try to dissuade you from spending more money.
Some would argue that the turbo isn't worth the extra money based on the HP/TQ increases or because of the added potential risk of one more thing that could break. These are valid arguments depending on the person buying - but you are leasing. You would be under the factory powertrain warranty during the lease, so in the event that the engine/turbo does have issues, you wouldn't be the one paying for the repairs.
Mainly though, the statement that running 87 would lead to premature fouling issues and turbo issues is not true at all. These engines were designed to run primarily on 87 and we have many users on this board who have been running 87 for years with no issues.
