This is my personal opinion too but when I put a cheap Chevron fuel cleaner in my, bought new Subaru Forester, I had a feeling that I drive a different car. Immediate response to throttle, more power. By that time I had 40,000 miles on the car.I've only used Techron as well. But the only difference it made was to lighten my wallet by $7 or so.
There's two. Fuel Injector cleaner, and Fuel System cleaner. The Fuel System cleaner is twice the strength of the injector cleaner, that's the one to use. Do it just prior to doing an oil change. And whether it's effective is largely dependent on the brand of fuel that been used; if mostly brands with good detergents, such as Chevron and Shell, there's little point (unless you're experiencing a fuel related problem); but if mostly discount & no-name brand fuel, it should help. I've bought it from Amazon, it's half the price than from an auto parts store.Which Chevron cleaner or is there just one? Thanks
Using Top-Tier gasoline eliminates the need for injector cleaners.What is the best fuel injector cleaner to get for Toyota's? I've heard good things about Lucas.
I use Chevron Techron when Top-Tier gas isn't available. Available at Costco by the case for cheap!I use Chevron Techron.
