Greetings, I have a lot of unused left over oil from various other cars. I have an unopened 5 quart jug of 20W-50 from my RX7, and some 5W-30 from my wife's ZX2. I really need to change the oil in my 1995 351, can I use this oil? It would be used in the warm, humid summer, and some of the fall.

 

well what does the engine sticker say? i use 5w-30 in my truck but its a I6 i can use 10w-30 as well

 

I don't know what it says. I'm at work and the truck is at home.

 

the 5-30 is fine but i wouldnt run the other stuff.

 

Thanks for the reply. What is recommended? I want to pick some good stuff up on the way home.

 

I searched for the best weight oil to use, but I can't find a relevant topic... Anyone have any suggestions?

 

10w-30 is recommended but I'd use what you have. I was pouring 3000 mile used oil in my truck when it leaked a quart a day.

 

Thanks for the tip Sean. By the way, what's up with the car in your signature now?

 

just mix it all up and use it like that. i've got an I6 and i run 15/40 because everything else around the farm runs it too.

 

Nice! that is what I was hoping to hear!
