Independent lab analysis · Whitehall, Montana · Since 1985
Find out for less than a tank of gas. An independent lab measures your engine's actual wear — then you pick up the phone and we walk through exactly what it means, with someone who's been reading these reports since 1985.
What arrives in the mail
Draw a sample at your next oil change, drop it in the mail, and an independent laboratory measures exactly how much metal your engine is shedding — iron, copper, chromium, aluminum, and eleven more.
$49.95Less than one tank of gas. One kit, one engine. No subscription, nothing recurring.
This is what comes back
Parts per million of every wear metal in your oil. Viscosity, oxidation, fuel dilution, coolant intrusion. The condition of the oil and the condition of the engine it came out of.
Then the part that matters: call us and we will tell you what it means for your vehicle, your mileage, and your driving — on your schedule, not ours.
The guarantee
Test your engine. Treat it. Test it again. You are not taking our word for anything — an independent laboratory is doing the measuring, and if your second report doesn't show improvement, we refund you. No argument.
What you're actually buying
We've been reading them since 1985.
Your report never arrives alone. Call when it suits you and we go through it line by line, in plain English — no appointment, no queue.
What's normal for a 40,000-mile turbo four is not normal for a 200,000-mile diesel. Numbers only mean something in context, and context is the part that takes forty years.
Treat it, watch it, or nothing at all — and we'll tell you when it's nothing.
No — that's the point. What you're buying here is a measurement, from a laboratory that doesn't work for us. If your engine turns out to be in good shape, the report will say so and we'll tell you so. We'd rather keep you for twenty years than sell you a bottle today.
You draw it at your next oil change, before the old oil goes in the pan — either from the drain stream or with the tube in the kit. It takes about two minutes and the bottle seals shut. Full instructions come with it, and if you'd rather have someone walk you through it, call us.
We ship the kit to you free. Sending the sample to the lab is on you — about $9 at the post office counter. Used oil can't go in a collection box with stamps on it, so it's a counter trip either way. We'd rather tell you that up front than have you find out standing in line.
Usually about two weeks from the day you drop it in the mail. The lab is fast; the postal service is the variable. Your report comes with our number — call any time between 8 and 5 Mountain, Monday through Friday, and we will go through it with you.
No. One kit gives you a baseline, and a second after your next oil change shows which way your wear is heading. For maximum results, and to know how long you can safely run your oil between changes, we recommend testing at every oil change. At $49.95 a kit, that's less than a tank of gas each time.
No. You're sending a sample of your own used oil to a laboratory — nothing is added to your vehicle and nothing is modified. Fleets have done exactly this for decades.
Then you've spent $49.95 to stop wondering, and you have a baseline — a number to measure the next several years against. Wear is a rate, not a snapshot, and rates only show up when you have more than one reading.
We do — by phone, when you call. Your report arrives with our number, and whoever picks up has been reading these since 1985. We keep it that way on purpose: you call when you have ten quiet minutes, not when it happens to suit us. 8 to 5 Mountain, Monday through Friday.
