I believe boutique oils probably exceed whatever the Dexos standards are by quite a bit.True. A Dexos rating means nothing because if it did Amsoil would have a Dexos 1 sticker

Can you provide a link to Valvoline's statement on this?Valvoline says VRP is their best oil but it is not a long drain oil .

They don't say that. They don't say don't use it for long drain intervals. They say follow manufacturer recommendations, which is often 5k or less for severe service, which most qualify for.Thanks Tired, but I meant the part about VRP should not be used for >5k OCIs
Do you need to do 9-10k intervals? 6k is too often?That was a big reason why I switched from VRP to ESP in my Civic. I wanted to go back to 9-10k intervals and I didn’t feel as if VRP was as capable of that as ESP would be. If I was doing 6k intervals then I’d be comfortable with VRP but beyond that I would need to do a UOA to confirm (and I haven’t done a UOA since I retired, my last company was five minutes away from the Wearcheck lab so dropping off samples was so convenient for me for those 14 years)
Don't want to stray off OP, but I forgot about SynLube! I'd have to go back and do some searching, but I don't recall anything using or getting VOA/UOA on it.
Thanks. I was concerned about my wife's 4Runner because it's now running VRP. I do 10k OCI's on it because her miles are almost all long highway miles. The maintenance manual recommends a 10k OCI.They don't say that. They don't say don't use it for long drain intervals. They say follow manufacturer recommendations, which is often 5k or less for severe service, which most qualify for.
Yes if you qualify for regular service intervals, which it sounds like she does, then I think it's ok to run for 10k. Which 4Runner? Honestly doesn't really matter. They all have had good engines.Thanks. I was concerned about my wife's 4Runner because it's now running VRP. I do 10k OCI's on it because her miles are almost all long highway miles.

6k is too often for me, especially in the warm months when I’m putting 160 miles a day on my Civic and don’t really have any days free when I can change the oil eitherDo you need to do 9-10k intervals? 6k is too often?
Con:
VRP might be a great product for cleaning up a dirty engine but what if you have a new(er) engine that may not need cleaning?
Are you planning on doing UOA after the 10K OCI?I do 10k OCI's on it because her miles are almost all long highway miles.
Quite often delivery from Walmart is not an option. In fact, right now it isn't. I can order and pick it up in the store on the 23rd, but delivery is not an option.Isn't Walmart delivering in your area ?
Yes. I should do that. I can tell you, so far, 3k miles in, the 4Runner's 1GR-FE engine seems to like VRP 5W-30. It feels smooth and torquey.Are you planning on doing UOA after the 10K OCI?
I'm interested how the VRP handles that OCI.
To substantiate further , look at UOA’s of vehicles that used VRP to check for additive levels (TBN) testing to see what’s left at a given mileage . While not a be all end all - it will give you an indication what mileage range VRP is good for .They don't say that. They don't say don't use it for long drain intervals. They say follow manufacturer recommendations, which is often 5k or less for severe service, which most qualify for.
I wonder if this could be used for the 9-10k intervals after the clean up. I'm not pushing for that and I myself don't do such intervals but out of curiosity I wonder if it would make it, especially if the manufacturer recommends a longer OCI like you are trying to do.
I have VRP in my wife's CRV now and I'm gonna run it based off the MM, not a specific mileage or time.
