I only use full synthetic mobil 1 in four diff weights for different vehicles and summer / winter use.. i find oil is cheap and engines are expensive. I do my own service as I dont want stripped drain plugs...
In the past many decades ago I bought conventional oil. And must have 20 to 40 quarts left.. i keep about 50 quarts or more of mobil 1 .
I have at times used 60 percent or 70 percent full synthetic and added dino oil for the rest.. that seems ok to use up the dino oil so its not wasted.
When you buy blended oil.. does anyone know what percentage is dino oil and what percentage starts as full synthetic??
I am curious even if I dont use it to know if its a good value ?
And would you be better off making your own mix??
I am sure on a commercial line its not two vats of oil with valves to adjust the proportions. I assume that additives are special to blended oils.
