Oil Analysis test results on our very own 2005 Toyota Camry

We are using our very own Toyota Camry to perform a full life cycle of oil analysis testing. We first tested the engine with 16,750 total miles on it and the Amsoil 5W-30 synthetic oil had been in the engine for 630 miles. We use Blackstone Labs for all of our oil analysis testing. We wanted to do some real world, unbiased certified lab testing of our own to help show the strength of these Amsoil products. We did not skew the results, or change any of the facts. The only changes made to the test results forms were to hide some personal information that was included. We hope these tests prove to anyone who reads them that our products are for real, and far superior to any other products out there on the market. Here are the results:

Test 1 - May 2006/630 Miles On The Oil

This first test turned out great. Now we know that this slightly used car has a great engine that's in good condition. We didn't expect to get any real information in reference to the oil since it had only been in the engine for 630 miles, but we knew it would be a good baseline test to show how the oil holds up from beginning to end. We are hoping the next couple of tests show some real work results here.

Test 2 - October 2006/ 12,990 Miles On The Oil

Test number 2 was very informative as well. It seems that some elements were found in the oil that may point to an engine issue that we will definitely want to monitor very closely. As you can see, the Sodium and Silicone amounts are increasing. We have been told by a Toyota service representative that these elements can show possibly two issues, a bad air filter or leak in the air filtration system, or the presence of coolant liquid in the oil. Neither of these issues are a result of running Amsoil however. In fact, the testing shows that the oil is still holding up extremely well and wear metals are still below normal levels for an engine at this age and mileage. In response to the Silicone and Sodium results, we have had the air filter changed (Wix is the only make of a fitted filter at this time so we got a new Wix filter installed), had Toyota check the air filtration system, and had the coolant system pressure tested. At this time, no issues were found so we must assume either the air filter was not working well, or the issue is too early to detect by normal means. We will want to test the oil again in about 3,000 miles just to see if the Silicone and Sodium levels increase or decrease. The EaO oil filter should be able to filter out most of the excess elements if we have stopped the introduction of them into the engine, but just to be safe we want to test again soon.

Test 3 - January 2007/ 20,766 Miles On The Oil

Since our last test we did take the car into Toyota and had a service pro check for coolant in the oil. None was found and after a pressure test the engine was found to be doing well. But as you can see from this test the silicone is still getting higher. So we had them check the air filter system. Once they dismantled all the parts that connect the filter box to the engine (about 5 pieces) it was found that the base of that unit was not sealing well and letting dirt enter the engine. This area was past the air filter so it was as if the air filter was not doing any good at all. Repairs have since been made but as you can see the silicone levels had already gotten too high. Test 4 should show if our air filter system fix will really make a difference. If nothing else, these oil analysis tests can help prevent a long term engine problem by allowing you to catch things like this. So far the oil is still running strong.
