A GUIDE TO BASIC DIY
ENGINE MAINTENANCE

Any auto technician will tell you that the best way to keep your vehicle’s engine running well is to keep up with routine maintenance.

It might seem intimidating at first, but with a little patience, practice, and basic tools, you can affordably take care of some of your engine’s most important needs.
The payback? An engine that runs stronger, longer, and is less prone to costly breakdowns.

SEA FOAM High Mileage

cleans and prevents harmful fuel residues and varnish

There are two significant areas in which Sea Foam High Mileage (or Motor Treatment) can help maintain your vehicle’s engine and those involve fuel and oil. For vehicles that are driven regularly, adding one or two cans of Sea Foam High Mileage to your gas tank every 2,000 to 5,000 miles will help keep your entire fuel system clean, lubricated, and protected.

Adding Sea Foam High Mileage to your crankcase before your next oil change can help clean harmful residues and deposits that can restrict oil flow and lubrication of critical parts.

COMMON DIY REPAIRS

ROUTINE MAINTENANCE IS THE EASIEST WAY TO ENSURE YOUR ENGINE WILL RUN BETTER AND LAST LONGER.

Some of the most important pieces of an internal combustion engine — and those most prone to eventual failure — are also the easiest to maintain or replace. Here’s a quick look at critical components that you can evaluate and replace if needed, without breaking your back or the bank.

how HIGH MILEAGE helps prevent engine problems

HIGH MILEAGE CLEANS AND LUBRICATES UPPER ENGINE AREAS TO HELP RESIST LONG-TERM WEAR.
High Mileage works through fuel injectors and carburetors to remove harmful residues and deposits from fuel passageways, intake valves, pistons, and chamber areas after years of harmful buildup. It works in oil to clean harmful oil residues that can restrict oil flow and engine lubrication.

QUALITY OF PRODUCT
SMOOTHER IDLE AND MORE POWER!
“I drive a Toyota Matrix with 247,000 miles on it. I’m a second owner on it, and maintenance has been kept up regularly by myself but not so sure about previous owner. Like any vehicle with this many miles, it has had a bit of a rough idle. I suspected the injectors might be getting dirty and possibly need replacement. I had run other fuel system cleaners through it, but it’s always been a bit rough. After running High Mileage Sea Foam, I’ve finally got it running smoother and it even seems to have a bit more power, which with this car, every bit of that counts. Super happy with this, and will continue to use on a regular basis.”

THANK YOU SEA FOAM
“This stuff did exactly what I was hoping it would – make the engine run smoother. I have a 1992 Sidekick with 233k that is regularly abused. It’s my gambler, trailblazer, and daily driver. I added the full bottle to about 1/8th tank of fuel and drove it “normally” for about 50 miles. By the end of the trip the engine didn’t feel near as rough at idle and my throttle response seemed better. I’m overall impressed with the product and would definitely use it again! Thanks Sea Foam!”
