Valvoline Restore and Protect Fuel System Cleaner??

[melk]

Picked up another 2 bottles, 1 went right into my Pentastar with a fill up of Exxon 87 and the other in my CTS 3.6 that gets Shell 93

 

[Sequoia06]

So ran my bottle in a fresh tank of gas on our 2023 Mazda CX9. Initially I put it in my fuel tank when it was 1/4, drove around 25 miles before filling up, then my wife took an 8 hour trip on that tank.

My thoughts are anecdotal, but the car 'felt' smoother at idle (based on steering wheel vibration) after running it those initial 25 miles, my wife noticed it felt 'peppier' after running that tank and I thought so as well.

EDIT: 2.5L Skyactiv G with 73k miles

Are you planning to do an oil change after running it? I picked some up (want to use it)and I still got 1k miles until a change.

I’ve done back to back bottles in my CTS and it’s smoother than it’s ever been.

@Carguy2427 would this be safe for motorcycle tank liners? I’m sure it is, just thought I’d ask. I’d like to throw some in my Victory. So far periodic small doses of Techron hasn’t affected it, so I’d assume Valvoline Fuel System Cleaner would be fine.

Yep! Perfectly fine.

Any idea what types of deposits Valvoline Fuel System Cleaner cleans in a DI engine? Would it have any effect on valves at all? Does it clean injectors better than PEA would?

I can’t imagine that any chemical that you put in your gas tank would be able to do any serious amount of cleaning on the backs of the intake valves. This is why the best plan of attack with DI is to start using one of the stronger Top Tier fuels right from when the engine is new and try not to ever stray from that very often. It’s always going to be easier to keep a DI intake valve clean than it will be to clean up a dirty one.

Exactly correct. Limiting carbon buildup and excess deposits during combustion throughout the vehicles life is the best way to help keep the valves clean. The injector tip is also a large issue in DI engines as it's directly inside the combustion chamber and easily gets covered in carbon causing poor fuel atomization, which the additive will help with. Which makes the engine more efficient and less debris getting on the valves from an inefficient burn.

Thanks. As for the injectors, would you say using a bottle of Valvoline Fuel System Cleaner every 6m/5k miles would keep the injectors pristine, even when not using Top Tier fuel?

It's less about mileage and more fuel quality and driving habits. City/stop and go traffic is going to cause more deposits vs highway driving. Every 3-5k depending on driving habits should be fine.

You know, I’ve kinda wondered if Valvoline Restore and Protect oil may reduce or prolong carbon build up on the intake valves in DI engines since it’s helping keep the entire engine clean. Thus the PCV system would be cleaner by default as well correct? Of course higher quality fuels and driving style certainly attribute to carbon build by a large margin. But I’ve been wondering that. The addition of a fuel system cleaner would of course play into that as well.

Valvoline Modern Engine … different chemistry - went away PDQ …

Just ran 3/4 of a tank through our '15 Forester today, ~300 miles, Plus a tank of cosco regular. 181k

Seems like it had some light rough running events when getting off of the highway throughout the trip. Seemed like it has a touch more punch.

Mpgs were high. Averaged 28.8. could be weather, seems to be happiest in the spring and fall.

To me, it feels like it did more than lighten my wallet. The fuel system generally has been left to its own devices, but top tier is common. Mpgs seem about 1.25 higher than normal, wife likes to drive 75-80, and 4 mpg better than the average over the previous 4k.

I've had fantastic luck with Valvoline Restore and Protect for oil consumption and if that's half of what I should expect , I'd be thrilled

Valvoline engineers have said that Valvoline Restore and Protect will help keep intake valves clean.



I queued it up to the relevant segment.

Drove an '03 Toyota Matrix with 230k miles to Iowa last week (1,400 mile trip) and thought that would be a great time to try this. I had already ran SI-1 several hundred miles prior so not sure what there was to work with. Plus, these motors are simple; no turbo, no DI.

Nothing really of note, the car ran amazingly well the whole trip. Worst tank was 30.5mpg that had lots of wind and elevation gain north of Sante Fe. Best tank was 37.3 going through KS. Not attributing the mpg for sure to the Valvoline but was impressed in general. At 78mph, that car runs at ~3100rpm, which was often on I-40 & I-80. Per Google, original mpg estimates for the car are 28/33. Although fueleconomy.gov says 25/30.

My use so far doesn't add much to the conversation, but putting out there. Will use it in our '18 CX-9 prior to next oil change. Hoping that someone will have some actual data and/or deposit removal proof with this stuff soon.

 

[hotpancakes]

I'm wondering...I've heard that Techron/PEA works best during many on-off cooldown cycles where the PEA has time to coat the injectors+valves (if non-DI), as opposed to long stints of highway driving without cooldown cycles. Does this Valvoline Restore and Protect Fuel System Cleaner work any differently? @Carguy2427 What driving cycle would you recommend for best results?

Got another 500 miles of highway cruising laid down on my 2008 GM 3.6 with Valvoline Restore and Protect Fuel System Cleaner in back to back tanks. I stick to Shell/Exxon/Chevron gas. Oil change coming due in another 1.5k miles

Started to grab another bottle of the new stuff - then noticed the last two Regane Hybrid for $7 each (PEA) so I quickly decided with an electric winch - my Jeep is a hybrid - and got both

 

[Wheel366]

I'm curious if I should throw this in the tank the next time I have a really long drive or just put it in and drive normally. Would it sitting in the tank and system soaking and slow use be better than it constantly burning until empty?
