I recently purchased the engine check up test kit,$25. You get 6 test patches ,like felt paper. One drop from the dip stick on a recently ran engine. I tested 4 engines
1.Two F250 Yamaha FS with ~3450 hrs. Oil changed at 3400. 50 hrs on the Yamalube 4m 10w-30.
OIL Looked very good.No water or fuel dilution. Will test again at 100 hrs ,oil change time.
2. 1997 Chev Truck 2500 FWD ,92,000 miles with 50 hrs using Shell Rotella 15W-40 Synthetic .
Also looked very good.Darkest of all the tested engines ,but still very good condition. No coolant or fuel dilution.
3. 1996 LT4 Corvette with 90,000 miles with 50 hrs on Mobil 1 10W-30. It has always had mobil 1. It came from the factory w Mob 1.
Oil looked excellent at 50 hrs. Cleanest test patch of the 4 engines .No coolant or fuel in the oil.

If you place your oil sample off centered you can use the test patch more than once.Just a small one drop.
Test results are readable in 30 minutes or less.

Above are two web sites. Read both. Spectral oil analysis could be used if you had a bad paper test to confirm contamination.Most large cities or trucking centers probably will have a spectral testing machine. My home town of Lakeland,FL has one. I believe they do all the Publix Supermarket trucks, plus many other private companies.

Allen Uhlers is the president of Enginecheckup. It won a NMMA award this year for innovative products.

I plan to test again at 100 hrs.

Contagious oil change 27 Mar 08 with 100 hours.Yamaha F250's using Yamalube 4M 10w-30.
You can see the oil is dirtier at 100 hrs vs 50 hrs. You can also get numerous test in one patch.
