So I just bought an AC oil filter and 6 qts of oil for less than $25.00. Why would I spend that same $25.00 to have my oil analyized, which would mean I still have 3,000 mile oil and $25.00 less than I had before? You can spend your $25.00 anyway you want to, I'll spend mine on new oil.
In addition, the professional drivers I know will not run the same oil after one day at the races. They say that an engine that can exceed the value of $10,000 is easily worth the price of an oil change each time it's entered into a competion.

Second like a trip to your Dr. oil analysis gives you a fairly accurate snap shot on how your engine is wearing if you have trouble such as small amounts of coolant too much Si .......

What I'm getting at here is, Why spend $25.00 to see if the oil needs changed and still have used oil and a used filter, when you can have it changed for the same $25.00 and have a new filter and new oil? I'm not saying your wrong, I'm just trying to understand the logic here. What if the results come back and then you have to change the oil, you then have $50.00 into the oil change.
It just seems to me that the same amount of money will get the thing serviced and one way won't.

Also I do not test a lot. maybe once a year and always at the end of an interval. Last test I found high Si. turned out one of the clips on my airbox was not closed letting in bad air. Would have not found that for another 30K. I do fully understand all i get is a data sheet with numbers but in the long run I know how long I can wait between changes and monitor how the engine is running.

all i know is im not trusting that engine oil life monitor anymore. i have an 09 crew with 17k on it and only had the light come on twice. so after 2 oil changes i had to take it to the dealer and have the whole lower half of the engine resealed cause all the gaskets started leaking oil. granted this may not be due to not having the oil changed more but i am not taking any chances im going back to the old 3 month 3000 mile rule!2009 silverado crewcab ls - VA

I have a buddy that has a landscaping business. He leases a Ford F-150 that he drives around for 3-4 years 150,000K + miles. He is a cheap bastard. He never changes the oil, EVER. Just every now and then checks the oil and adds oil. He has never had an engine problem.

I lean towards the conservative and try to change around 3 mo's or 3k miles. At the same time, the easiest way to know if the oil needs to be changed is to check the dipstick. If it's dark, it's ready to be changed.
Does Slick 50 still exist? I used that in the past to coat the cylinders. I use Mobil 1 synthetic, but would like to put something in to help maintain the motor.
