2007 Honda CR-V, 200,xxx miles and coming up on needing it's next oil change. The engine is a tad noisy now that it's colder out (tick tick tick) and I was wondering if STP oil treatment is safe to use being that it has variable valve timing. Thanks!

I wouldn't use it. Too thick and will likely just sit in the bottom of your oil pan. I'd go with a high mileage formula oil, good luck.

I'd try an OE filter first if you aren't using this, and then I would try a High Mileage oil like Valvoline Maxlife first.

Skip the STP treatment. If anything, I'd say maybe go a bit lighter weight.

K24 is no church mouse to begin with that's for sure. If your valve lash is in spec (noise is probably piston slap anyway) then I'd just live it with that little NVH issue.

Won't hurt anything because it doesn't actually do anything.

There are varying opinions on whether it works, but is it “safe”? Yes. It’s just overly expensive thick oil. It will completely disperse into your oil. Just warm your engine up before you pour it in. If this is a quick check before you change your oil, go ahead. The better way would be to change to a higher viscosity oil as it would have a better additive package. I don’t use the stuff but I have witnessed an engine get quieter as STP was added. That must have been a case of excessive wear in the lifters in an older engine. Report back to use on whether or not it made any difference. smile

If you want the job done right......do it yourself.

Skip the STP additive.
What oil are you running currently? Per owner's manual or something more viscous? If using a 10w30/10w40, then try a 5w30 Valvoline Maxlife, or any other synthetic blend 5w30 in High Mileage formula. If you are on conventional 5w30, then a synthetic blend 5w30 could definitely help with the cold noise.

P.S. If it was mine - I would run Mobil1 0w40 in it until the engine/tranny quits, or until it gets totalled/sold. 5k OCI with close eye on the oil level.

What grade of oil is recommended for your CR-V and what grade are you using? I believe it is 5W20
You're always going to get several different opinions here so, I'll add mine too.

Don't use STP or any other oil additive in your CR-V. Do in fact(if anything) use a thicker oil(not thinner). And what I mean by thinker is...
...if you're using a 5W20, change to a 5W30. I do agree with using a High Mileage Oil as they seem to run a tiny bit thicker in their specific grade. And again, I may use a 5W30 High Mileage oil which is still decent for winter use.

I'm currently running 5w-20 which is what is specified. Looking at the old maintenance logs in the owners' manual, the previous owner used 5W-30 a lot. Interesting

Safely use it, yes. Will it do anything for you is another question. Try it if you want, but I agree with Char Baby.

I would pass on the additivesnd go with a HM oil like Valvoline Maxlife or the brand you prefer and in 5w30.

I have a 91 dodge Dakota 4cy 5 speed that will not quit. It does use oil. If you run anything other than 5/10W30 in it there is a lifter tick that last for a while after starting. If you try to use XW40 or HM oil in it to cut the consumption the lifters DO NOT like it. But 10W30 and STP 4CY , no tick, oil consumption cut in half. It is NOT sitting on the bottom of the pan. It is doing something. I may be one of very few, but for me it works

A gas station near me sells STP oil treatment for $1.50 for a 12 ounce bottle so I'll go ahead and try it. I'm honestly more curious than anything now of how good it'll work if it will at all. I'll definitely report back in a few days
