OIL oil OIl, sigh, growl, vomit
I have been reading these message boards (ford and toyota, cannot find a silverado board) for quite some time. The topic of oil is the common thread, people are looking for the Magical Fountain of Engine Youth This is what my vast life experience in life has taught me.
People choose an oil more out of superstition than anything else, "my father used Valvoline, so did his father, they only drove Fords, and they got over 2.5 bazillion miles out of em', they bought a Chevy one year, it only lasted 300 miles and it was sitting next to the barn for 20 years, with only 300 hundred miles"
Of course that sounds familiar, we all either know this person, or we are this person.....myself included.
I use only valvoline, 10-30, change the oil every 3000 miles, I have never ever had an engine failure....EVER!!! Why do I use valvoline?????? As a kid, I used to poke the holes in the metal oil cans and be in charge of switching the pour spout from can to can, I only saw Valvoline, did not know another oil existed till I started driving cars myself, I dare not try another brand though, the OIL GODS would strike my engine DEAD.
Oil technology as well as engine technology has progressed over the years, engines are more efficient and oils are more slippery. the only wrench that can be thrown in rock solid Valvoline 10-30/changed every 3000 theory is the synthetic engine oil.
I have yet to assess how the engine oil gods feel about synthetic oil, they may be very displeased with me for using it, and strike my motor down, I have yet to try it. Depending on which full size truck I buy, I will use synthetic. THIS IS MY EXPERIENCE WITH SYNTHETIC OIL AND WHY I AM SOLD ON IT>>>
I used to be an H-60 Seahawk rescue crewmember (same thing as the Army Blackhawk), The turbine engines use Synthetic fluids only, and here is the kicker, You never change the oil in a turbine engine. That engine (two actually) runs 20,600 rpm constant, the only thing that changes is the amount of fuel delivered to maintain those RPM's. 20600 in the blistering heat of the sandy Persain Gulf, to the blistering heat and humidity of South America, to the Blistering cold of Alaska. The only oil maintenance that is performed is adding oil, so it is in the proper range, and sending the oil out for analysis every xxxx hours of flight time. These engines turn for THOUSANDS AND THOUSANDS of hours at 20,600 RPM and the oil is never changed...
So what does all this mean??? Turbine engines are amazing pieces of efficiency, they do not suffer the blow-by problem of our less efficient internal combustion piston pushers. Turbines (at least mine) operate at one RPM range and do it well. (just like your dad said, do one thing, do it well) and above all, synthetics stand up to their extreme heat and climate conditions, never needing to be changed.
Use synthetic, use dino oil, just change it regularly! sorry you had to read through all that to get to the final statement.
