I've driven a Saturn since I was 17, so I always used regular. Does anyone see a difference whether you use regular or premium for your CLA? Does it matter? Thanks!

Use premium. Given the cars compression ratio, it does matter. If you want optimal performance and fuel efficiency, you will use premium. Its my understanding that regular will not hurt your car, but your car's computer will have to readjust to make up for the lower octane so that it doesn't ping, and that will lead to lower fuel efficiency and less power. This is all information I've been told by reliable sources over the years (articles online, Car Talk, etc), though I myself am not a mechanic.

Np. Sorry I thought you were messing around. It's a thread/posting that stays at the top of a page for FAQ, or guidelines or special announcements.

Look up Top Tier Gas. It will give a list of companies in your area that meet strict requirements for today's engines.
