3. Techron, 2. BG44k, 1. Royal Purple Maxclean .... these are the top 3 that work for those who don't want to wade through the video. Starts at about 8:48.

Red Line SI-1 for 30 years with no issues

You show Redline SI-1 three times during the "alcohol" warning segment. It has no alcohol.

Redline has the highest percentage for of PEA! The only thing that actually cleans.

None of these comparison videos ever mention Liqui Moly products, probably because Liqui Moly is a German company.  I own a 1997 Chevy Cheyenne 4.3 V6 have used Liqui Moly additives for almost 20 years have 326K on the motor and it still has perfect compression and runs like Swiss watch.  Any of you guys unfamiliar with Liqui Moly please check them out their additives are wonderful.

Use of Top Tier Approved Gasolines help a lot too...

30yr mechanic here..only ones that work contain PEA..nitrogen based cleaner. Best one out there is BG 44K, expensive but works

I use Techron every 5,000 miles, my car still runs like new.

Lucus is the only injector cleaner that works it finally got rid of the multiple engine misfires code

Can't go wrong with Techron, use it all the time, I buy it when it's buy one get one half price

Proved Redline SI-1 in class at UTI with 5-Gas verification. Otherwise BG 44K.

I am surprised you didn’t show Lucas fuel cleaner. I’ve used it for almost twenty five years in all of my vehicles, gas, diesel including lawnmowers and never had an injector or carburetor problem.

I like the royal purple maxclean   I use that in my 1998 dodge Durango V8 360 5.9l I tell you I'm never getting read of my dodge Durango I really love the way she drives she has over 365.000 miles on her and still running good

Repairs are expensive, go with the BG Platinum 44K and if you have a higher mileage car go with Valvoline Restore and Protect. It's a full synthetic oil that you use for the life of the car.

Berryman ChemTool B12 has been my go to for years and countless miles.

I use Techron once every six months on my 2018 car. Only 90k miles on it but that meets the definition of "high mileage" so better safe than sorry.

Redline’s fuel system cleaner from what I understand actually has the highest concentration of PEA’s and is a bona fide fuel system cleaner!

I didn't see Lucas.  I've been using it for decades in many vehicles as well as my boat.

I have a RAV4 with the 2GR V6 engine, and a 16 gallon fuel tank. Every fill-up, I add my own blend of 5oz MMO and 5oz Lucas. Keeps mileage up, deposits down, plugs clean, and all the moving parts of the fuel system lubricated.
