I sent an oil sample from my 1993 Nissan Sentra 1.6 lts to Blackstone Laboratories, the same one suggested by Bror Jace and the results came this last Friday, Dec.19 '03.

The oil was Amsoil 10w-30 synthetic with 5,809 miles of use.

Blackstone Labs. sent me an e-mail with the results and according to them my car is wearing according to the averages of my car and there are no indications in the oil of problems. This is a copy of the comments I received about my car from Blackstone Labs, included with a table with the results of the tests performed to the oil I sent:

"PABLO: This was Amsoil's 10W/30 oil, which explains why the viscosity read high. Amsoil's viscosities often run higher than the "normal" range for other gasoline engine oils. We didn't find any harmful contamination in the oil from moisture, fuel, or coolant. Wear levels read right around average for a Nissan 1.6L engine. The TBN read 6.8, so the oil certainly has plenty of active additive remaining after the 5809 miles you put on it. You could go longer on the oil, and as well as the engine is wearing, the mechanical parts can take it. Try 6500 miles next time."

EQUIPMENT MAKE: Nissan
EQUIPMENT MODEL: 1.6L 4-cyl
FUEL TYPE: Gasoline (Unleaded)

OIL USE INTERVAL: 5,809 Miles
OIL TYPE & GRADE: Amsoil 10W/30 (Gas)
MAKE-UP OIL ADDED: 0 qts
OIL REPORT

And, the testing costs only $30, $20 if you don't want TBN testing, plus the postage for sending the oil sample. This laboratory provides you free of additional charge the bottles to send the oil sample. I used Priority Mail from the US Postal Service and it took two days for the oil sample to arrive to Indiana, where Blackstone Labs is located.
