Valvoline R&P, Honda K24, 250k miles, report on progress
- Thread starter slo town
- Start date
Very nice sequence of events cleaning that baffle in less than 8 thousand miles. That Castrol did its job for sure when opened up to do your valves. A couple guys I work with in there 60s swear on Castrol products keeping internals clean when opening the bottom and top ends. Keep on trucking....

Really? Something must have changed in the K24 tuning on the CRV's. I've driven all generations except the newest ones and they're great vehicles - but glacially slow.
I wouldn't say the the K24 powered Elements or CRVs are glacially slow. Instead, I'd define their power as being "adequate". What I've noticed more than power is the brakes. With four people in our Element it takes noticeably more brake pedal pressure to slow the car (I use Honda OEM rotors and pads).

Which also makes them great for the new drivers. You learn to leave some room to get to speed, not cut off others. The higher seating position, space all good. My son had a high mileage, hand me down '04 as his first vehicle. AC seized up needed repair so it was down for a bit and he got a Forte instead. Fixed the '04 and my daughter had it for a bit also learning on it until tranny went at like 270k. Ran great but needed something else. Sister handed down the high mileage '08. Daughter loves it everyday.

It's probably just the transmission on the old ones. They just don't feel like they want to move. You have to really stick your foot in it to get it down shift once, I don't think I ever had my 2012 double downshift but I have a light foot.
Great report! I have a '14 TSX with a slightly revised K24 (K24A1 vs K24Z3) and am also running 4 (very short) OCIs of VRP 5W-30 on my low mileage car "just because". My bigger question is where in the world are you still getting German Castrol for the last 100K miles??? 
This post - particularly the cleaning of the varnished baffle - inspired me to go check that same area on my K24 (2014 TSX w/ 30k miles I recently purchased at 25k miles). Yours actually maybe cleaner than mine with 220k less miles!!!!?
I’m on my 2nd OCI (about 600 miles in) of VRP 5W-30; 1st was very short with VRP and HPL EC30 for 2k miles and this one will be 2500, and 3 and 4 will be 5k miles each. This car was dealer maintained but presumably sat for very long periods of time or super super short tripped so the CARFAX showed 7 to 7500 mile OLM change intervals with that being 2-3 years on average.

I've been using Kirkland in the wife's cr-v since around 100k and she is at 169k now. Most all changes were 5k or less with the exception of one dealer change which was higher and I'm pretty sure I did longer OCIs with the 2 Amsoil SS changes I did and possibly a longer one with the one HPL OCI. I have I think 5 jugs of VRP with a few 0W-20 and a few 5W-20s. I am thinking about using at least 2 of the 5W-20 next. I don't have any noticable burning issues but I figure it can't hurt to clean things up a little. Maybe I'll go for a 3rd and 4th after but we'll see. Then, I would go back to Kirkland to finish up my stash there. I usually go by the MM which ends up being around 7k miles depending on how many city miles the car drives. Oil changes are usually 7 months when it is warmer and then 5 months when it is colder. I can only assume that is because she remote starts more and for longer in the colder months, a habit I have been trying to get her out of but have been unsuccessful.
Wow, color me impressed. For "marketing" (ah yes, I 'member all the exshperts screaming from the hilltops that it was all hype and marketing) it appears to do a pretty good job at doing what it says it will do.
Maybe the exshperts can chime in with a new theory to hate on it. I know, lets all claim that it weakens steel and iron and other metals......

Try a 2016 in Sport mode with the engine fully warmed up.
It might help that I keep the injectors clean by using Red-Line SI - 1 in the fuel, and PUP 0W - 20, and I have changed the CVT fluid 4 times with Honda fluid ( I know, overkill ) and rear end fluid twice, cleaned intake air sensors, new PCV, on it's 3rd oem engine air filter, antifreeze drain and fill with Honda premixed, Hunter alignment and tire pressures proper.

The K24 cannot be praised enough. I have a K24 powered 2013 Accord with 236,000 on it and it runs like a clock. I run 5w-30 in Florida and it barely burns any. I fill it and dont have to add any between oil changes. I keep a close eye on it and give it the smell test for dilution as it's GDI. I drive it 23miles one way to work in a hot climate so I know I'm not at major risk. I have sent it off for a UOA and no significant dilution. Some sure but nothing to bat an eye at.
The mighty K24 for the win!
I've owned a 2011 Acura TSX wagon from new. Got a notice from Acura warning about oil burning due to problems with the low tension piston rings with a warranty extension and a recommendation to switch to Top Tier fuel. I was using Mobil 1 0w20 and following the maintenance minder but found I was down about a quart 6k miles after my last oil change in 2016 @ 70k miles. I changed to a 5k OCI and used Techron for a while and since then only Top Tier fuel. Replaced spark plugs and adjusted valves @ 90k miles and the cams and everything under the valve cover looked perfectly clean. Had no way to look down the spark plug holes. Oil burning increased to about 1qt every 4k miles until about 2022 @ 104k miles and then 1qt every 3k by April 2024 @ 124k miles. Extended warranty is long gone, but they wouldn't have done anything until I was burning 1 quart every 1k miles. That's when I switched to Valvoline Restore & Protect. It's now July 2025 @ 132k miles and I've used about one quart in the last 5k miles. Third oil change with Restore and Protect is due in a few thousand miles. Things seem to be going in the right direction. I have a 2007 Accord V6, 6sp coupe and it doesn't burn any oil. In fact none of my cars since a 1977 VW Rabbit have burned any oil, and that car had a recall for bad valve stem seals which fixed the problem.

Great feedback! I’m debating using VRP as my forever oil in mine.

Has anyone with a K24 used any particular oil that changed anything with the VTC actuator rattle on start up?
Yes! I’m not sure why we all aren’t running VRP? Prevent burning or ring build up in newer vehicles and to clean up older vehicles. There will is no downside.

Yes run a thicker oil instead of 0w-20 run 5w-30. The oil builds pressure faster and it doesnt drain out of the VTC gear as much so it quiets down the rattle. I have two K24 powered vehicles and a k20. One of the K24's had the rattle until I moved to 5w-30 and I haven't, except very very very rarely, heard it since.
Got my VCT actuator replaced under warranty and the problem never returned. It only happened when temps were below 20F. I’ve only ever used 0w20. I don’t know how well 5w30 would flow at those temperatures. I suspect the part has been improved.
