No. It ensures that filters aren't clogged resulting in trashed engines that would be blamed on Valvoline. Need to catch up on the threads full of info here.It also ensures Valvoline sells 4x inventory. Just say'n.
Valvoline Restore and Protect
- Thread starter Scott S
- Start date
I ran Valvoline Restore and Protect inside two cars with a 5k mile interval.
I had tax money and bought oil filters I thought would work well with Valvoline Restore and Protects cleaning ability.
Mobil 1 Extended Performance, AMSOIL, BOSS, and MicroGard Select EL
Now after 5 intervals, I feel good about the condition of the engine.

Just got a jug of Valvoline Restore and Protect API SP with the red sticker "Voted Product of the Year 2025". It will be waiting for my next oil change.

I posted pics of the oil and filters frequently but I wish I took good before/after pics, I have some now of the Ford fill hole which is super shiny. I would love to look around with a boroscope .
Some pics of the oil fill hole on a 03 Focus with 174k miles
Next intervals will be back to good old Mobil 1 Extended Performance

guess i'll have to look it up again...
update: this is a Honda 1.5T L15CA. 2023 Civic Si. I just looked at a generic engine builder clearance/oil weight chart. what do you think?
left column is "Standard or New" and right column is "Service Limit"

Very nice
I think it in no way requires a low viscosity oil.

very informative.
See post 3,153 (LINK). If a 5.0L Coyote V8 can run anything from xW-20 to xW-50 based on just journal bearing clearances, so can your engine. As said earlier, "tight" bearings can run thicker oil, but "loose" bearings don't like thinner oil. Note that the clearance has to be compared by clearance per bearing diameter, which the Coyote has larger diameter journal bearings, so the clearances are just a bit larger but still plenty "tight". I'd run a good xW-30 grade in your engine if it was mine, it's going to provide better MOFT and wear protection.
Thank you for posting the link to the post

What makes you feel good about it?
A friend of mine “accidentally” went 22,000km on an OCI of Valvoline Restore and Protect 10W-40 in a 2012 Mazda3 2.5L.
To be clear, the sludge and deposits seen through the oil cap were there before the last OCI.
I had been running short intervals of a cheap oil (Shell Helix HX7 10W-40) to try to clean it up, but then I put Valvoline Restore and Protect in last time to see what would happen. Unfortunately, that turned into a real-world worst-case test of Valvoline Restore and Protect’s filter-loading capability.
I don’t think anyone needs to stress about doing early filter changes at normal OCIs. Just leave the filter – it will be fine!

Looks like chocolate pudding
Hope Valvoline Restore and Protect can do some work at least for 4 OCI. That engine looks horrible - it's full of sludge and varnish.
Is that your engine or your friend's engine?
I'd pressure test that cooling system and make sure it doesn't need a head gasket.
It doesn’t use a drop of coolant. It did go over 60,000km without an oil change though, and has had a terrible OCI history in general hence the sludge.
Friend’s engine. Not mine!
No coolant use, that means pure neglect then.
