The severe service OCI for that Kia is 3,750, and it is under a recall that extends warranty to 180K, but they get picky on OCI to honor it. Also, I am retired, so my oil is cheap due to the fact I have the time to look up all the rebates, sales, etc. Also, getting under cars often keeps me...

Local Walmart still at $29.97 in stock for local pickup and shipping.

They do have innovations in motor oil, but they are primarily a brand marketing company.

This new report shows an oxidation value of 78 at just over 3,400 miles. Any thoughts on why? I have emailed Polaris about it but should hear back in the next few days.

That is impressive. Though I think R&P, based on it's marketing, hasn't been formulated for long OCI. I would be more comfortable at 5k to 8k miles.

I've never seen a shortage not followed by a glut.

With 5K oil changes probably fine. Most of the Euro formulation differences seem to be for long OCI's, but the viscosity difference is there, too. The wear metals like fine though.

My understanding is that all octane versions of a given company's gas brand uses the same detergent additive pack in the same quantity, regardless of what the marketing on the pump may have you believe. EDIT: Shell does vary the detergent on different octanes level. As I just discovered today.

My last order coming in on price but a day late on delivery.

My area still has it and still $8.48. I bought 4 jugs yesterday and 4 today. The trick is: you have to order on-line for pick-up at the store to get the price. No idea why. It is the 5quart and it is Castrol Edge Euro K (5W-30)

Got my kit from Polaris today via UPS. Was impressed with how well this promotion was executed.

If it is at idle, clean the throttle body. If at cruise, double dose techron for 2 tanks. If that doesn't work, look at slow O2 sensor or injectors. If scan tool show less than 10% negative trim, you can just live with it.

You give it all the passwords and permissions to do that and you risk exactly that.

Given both wear, and oxidation and nitration values, Valvoline Restore and Protect gives an impressive performance in that engine. Something I have noticed as well. #1-4 is Valvoline Restore and Protect, #5 is Castrol EDGE Extended Performance 5W-30 hence the titanium.

Thanks. This is very interesting to me, I have a 2019 Sedona with the same engine and 98,000 miles. You must live somewhere with cold winters, given the fuel dilution variance.
