I have a 2012 Volt that was new and have always used premium gas but I've been told by other Volt owners that they switched to regular and have had no issues. What do you think?
The engine is totally different between Gen1 (1.4l) and Gen2 (1.5l). Gen2 is specifically tuned to use regular. Using premium in the Gen2 is a waste of money.But the newer volts are setup to run on regular gas does this mean that something changed in the engine for the fuel injection system?
My son is driving a G1 and moved a while back to be 1/2 between his wifes work and his work. He burns gas daily but dramatically less gas. With that driving he also did the comparison of using premium gas (better MPG) and regular (less MPG) and determined regular was saving him money.I have a 2012 Volt that was new and have always used premium gas but I've been told by other Volt owners that they switched to regular and have had no issues.

As I recall GM also claimed that premium gas was more stable, did not degrade as quickly as regular gas in the fuel tank. This was considered important given that most Volt drivers use so little gas.The gen1 volt does have variable valve timing. also called cam phasing, to assist in low speed torque. I have been running 87 exclusively for the last 10k miles, I typically use 2gal per day. FE is around 35 on a bad, cold, windy day up to 44 under good conditions. http://ecomodder.com/forum/em-fuel-log.php?vehicleid=10178
Think about it, premium gave more mpgs and this car was sold on efficiency. They HAD TO require premium to ensure the EPA tests showed the best FE.
