In the text below the youtube video it has directions on how to determine if you need a higher viscocity oil than what the manufacturer recommends, but by the time you made the determination you would have over 30,000 miles on the vehicle.
Is it really that big a deal? I use 5w-30 ... it's relatively warm where I live, I park in an insulated garage at night.
Here is the proper framework for making decisions regarding oil.
Step 1 - Utilize the OEM recommended oil and do two early oil changes during the break-in process (500 to 1,000 miles and again between 3,000 and 4,000 miles). If the engine is already broken-in, skip to step 3.
Step 2 - Take used oil samples at each oil change to establish the trend analysis.
Step 3 - Go 5,000 miles on the third oil change and take a used oil sample. If the wear rate per 1,000 miles is below 5 ppm, you are good. If the wear rate is between 5 ppm and 10 ppm per 1,000 miles, go another 5,000 miles on the OEM recommended oil and resample. If the wear rate is still greater than 5 ppm per 1,000 miles, then move to step 4.
Step 4 - Review the used oil analysis data to see if the OEM recommended oil is falling short in any aspect (low viscosity, additive depletion, higher wear rate). If it is falling short, try a different oil of the same viscosity that meets the OEM spec. Go 3,000 to 4,000 miles on that oil ............
Step 5 - Since the change in brand did not get the wear rate per 1,000 miles below 5 ppm, use next higher viscosity grade of whichever oil had the lowest wear rate per 1,000 miles. If it was the non-OEM brand, resample at 5,000 miles to check the wear rate per 1,000 miles. If it was the OEM brand, you will need to use it for 3,000 to 4,000 miles to flush the non-OEM oil out of the system before going 5,000 miles on the higher viscosity OEM oil to take another sample.
