Stop Guessing. Start Knowing.
Used Oil Analysis Pays for Itself—And Saves You More Than Just Money.
At SPEEDiagnostix, we analyze thousands of oil samples each year—and here's what we’ve found: Over 90% of oil samples show the oil was changed too soon. That’s money—your money—literally getting dumped out with good oil.
The math doesn't lie.
A typical full synthetic oil change (5 quarts) costs $75–$100 depending on your service provider (larger sump engines drives that cost higher). Do that 3–4 times per year, and you're spending $300–$400 (or more) annually… even if your oil didn’t need to be changed.
Used Oil Analysis Provides:
- Professional Laboratory Analysis - Make informed decisions based on science, not speculation
- Insight into engine wear, contamination, and remaining oil life
- The confidence to extend your oil change intervals safely—often 1.5x to 2x longer
- Spot early signs of engine wear before they become expensive failures
Take advantage of the fact that oil filters become more efficient with age—changing them early actually resets their performance (lower efficiency).
You don't have to change your oil to take an oil sample!
Using the vacuum pump, a sample of the oil can be taken via the dipstick tube. This allows you to take a sample and get your results before doing your regular oil change. Based on the results of the sample, you can make data-driven decisions - extend the oil change interval, change the oil now, change the viscosity of the oil, etc....Because you might have more than one car, you can also add an additional sample bottle to the kit.
The FedEx return envelope can hold up to 2 samples, so one kit can service more than one vehicle.
