Anytime the oil change is due

I use it after every oil change. Works great.

I have used Amsoil products for over 20 yrs now. All my boats, cars, trucks, snowmobiles, lawn equipment, if it uses oil and I own it it will have Amsoil. As long as this company continues to outperform in product perfomance and customer services I will continue to be a dedicated customer. 5 stars! And to think I got nothing to write this review Good job Amsoil! keep it going!

I add product annually. I noticed a good improvement in performance and fuel economy immediately.

Love this product, started using at every pil change. Smoother idea and improved gas mileage.

This stuff helps keep up maintenance on your vehicle and just adds that extra step of preventative maintenance. I had a gummed up injector and this stuff cleaned it up right away.

I got it because i liked what Alex at LSC said. Didnt effect my car to much, but it is newer. My wifes however, it improved nicely

Better fuel economy after using

I use Amsoil PI in my Direct Injected Subaru Crosstrek as well as my Mitsubishi Mirage and 3/4 ton Chevrolet (which don't have direct injection). It seems to be doing a good job of keeping my fuel injectors clean/ engines running efficiently. Upkeep is key and so I've been using this on my vehicles since they were new. Idling and throttle response are good with all engines.

I use this on every oil change along with the upper seller lubricant keeps car running tipped up if it works don't change it

Throw a bottle of this in the tank the Next time you fuel up. Incredible fuel system cleaner !

My f150 sets a lot nowadays so I add this to help with lubrication

We notice a definite improvement in performance, gas mileage and how smooth the car runs after we use it!

Here’s what I’ve got: 2016 M-B E400 4-Matic with direct injection and 23,000 miles on the clock Results: Increase of 3 mpg City / 2 mpg Highway Summary: Enough said.

I love this product and put a bottle in every oil change.

With this additive my somewhat rough idle and poorer performance faded away . Now 80 mph is no problem when needed on the expressway .

Buy the best leave the rest.

Works very well !

I put one bottle in my 2020 Ford Edge ST because I haven't done any additives since new and I'm at 40,000 miles. One bottle and I saw a difference at once about 4 gallons went through the engine. My average gas mileage went from 19.4 mpg to 21.6 mpg And highway mileage is at 29mpg which it's never been that high. Well worth the price!

Left for Florida pulling 25ft RV. Put 2 bottles in the 36gal tank. I can't prove any improvement but it never missed a beat in 1450mi
