Is this where Lucas fuel upper cylinder lube with injector cleaners work?
Pretty sure this stuff is for cleaning your injectors, I am not sure about it cleaning off the carbon buildup, id recommend doing a walnut blasting around 60-80k miles. Probably find shops that does it way cheaper than the dealership. Some say catch cans help with the buildup, either way eventually you will need it done or your vehicle is gonna run like crap the more it builds up.
). Then maybe have them checked around 80-100K miles unless you notice performance or sluggish running. Just my opinion.
imo, use Tier 1 gasoline brands, use FULL synthetic oil that meets Fords spec's and change oil & filter often (for me every 5K miles). I do the old Italian tuneup often (stomp on it when safe on freeway and on-ramps
I use the upper cylinder fuel treatment with injector cleaner in all my mowers and diesel tractor to keep water emulsified and etc and run ethenol gas in them without problems. I have not used any in my hybrid Maverick as I just use tier 1 in them. In any case this link is from Lucas Web site.
Whereas your hybrid Maverick is port fuel injected, it's unlikely you would ever experience build up on your intake valves as they get continuously cleaned by the injected gasoline washing over them as you drive. Direct only Injected engines get the potential build up because the gasoline is directly injected into the combustion chamber, not through the intake valve port. EDIT: This is why cleaner burning fuel and higher quality oil (less turbo blow by) are the most important things you can do to prevent carbon build up. Top Tier gasoline is recommended in both the hybrid and EcoBoost models by Ford. Supposedly, the 2025 Maverick EcoBoost has both Port and Direct fuel injection. This prevents the build up problem.
I used AC Delco Top Engine cleaner in the 1960s to remove lead deposits on valves at the Chevrolet dealership where I worked - hundreds of cars with 99% customer satisfaction. I was the shop foreman at the time. This stuff always increased engine performance and cleaned valves. It worked great back then and the reviews on Amazon and elsewhere give testimony to it's ability today. Based on my experience this issue is a tad overblown. In the 60s the smell that the product emanated was like soap and dissipated quickly after use. Check it out.
Back in the 60's those rigs all had carburetors and that cleaner DID get sprayed on the back of the intake valves if it was in the fuel. That's not the case with a direct injection engine.
There are plenty of directions and videos showing application at the throttle body. It works. I don't recommend fuel tank treatments.
Agree with Old Ford Guy. Top Tier, good oil and 5K oil changes are helpful, I'm not sure full synthetic is needed if you change at 5K. The full synthetic is great in it's ability with thermal breakdown and can last longer but doesn't really run much cleaner when burned, or at least not enough to warrant the cost. Catch can makes sense too.imo, use Tier 1 gasoline brands, use FULL synthetic oil that meets Fords spec's and change oil & filter often (for me every 5K miles).
