Can I mixed unopen single quarts of 5-20, 2-30,10-30, 30 W oil together for a single oil change without damaging the engine in a 2003 Ford Ranger 4 cylinder with 65K miles or a 1999 Toyota RAV 4 with 50K miles both requiring 5-20 oil?

Not advisable, but, … I know a fellow who buys drippings from one service station - you know, service dumps oil from cans quickly into customers cars and than places cans up side down, in a funnel, placed onto the empty oil barrel. He drives a ‘98 RAV4 since it was 3 years old using those drippings. Currently, his odometer just passed 300,000 km. and still car runs fine! Just, sayin’, …
F.S.
Don't do it. Not only the weight is different, the additives of each oil (if they are different brands) have different additives in it.
This can cost you two engines in long run.
Take it from Scotty, "oil is cheap, engine repairs are expensive!"
Never ever do this.. is my warning to you.
And I think everyone else on here.
Different grade .
Different detergent can cause the engine to wear out over time.
With old oil we use it to paint the fence .. it probably outlawed now ..
Agree with Mods and others. No.
But are you sure those two vehicles require 5W-20 oil?
Seems like those years are the 5W-30 generation.
