Check this out for Synlubes viscosity:
Viscosity at 40 degrees Celcius is 100
Here are some conventional oil's that have the same viscosity or come close.
Valvoline 20W-50
Viscosity at 40 degrees Celcius is 100
Bradd Penn 20W-50
Viscosity at 40 degrees Celcius is 97.1
This is telling me that Miro's junk is a 20W-50 oil, maybe that's o.k. for the summertime, but try starting your car in the wintertime when its 0 degrees outside.
My 1983 Chevrolet El Camino calls for 10w30, even cars in the 1970's called for 10w30
I think cars in the 1960's may have called for 10W-40
His oil is almost twice as thick as Pennzoil Platinum 5w30 at 40 degrees celcius, I think Pennzoil Platinum 5w30 is like 57.6
No wonder these used oil analysis with Synlube look terrible, we all know that 85% of our engine wear is on startup or as Gary Allan says during the 1st twenty minutes of driving, you want an oil that can flow as fast as it can on startup to lube all of the parts in an engine.
How do I know, I remember starting the El Camino back in the 1980's on conventional 10W-40 in 15 degree weather, it barely started and made funky noises, I went to Mobil 1 5w30 for the wintertime and no more hard starting or noises, summertime was Mobil 1 10w30, the Mobil 1 flowed faster than that conventional 10w40 oil.
Using Miro's oil is like having 20W-50, I do not care if his junk is synthetic, a thinner synthetic oil is still going to flow faster than a thick synthetic oil.
