So I watch scotty video on how to preserve car for long periods of time 

I forgot to do two most important thing 

Oil stabilizer  and car jack 

So I need your recommendation should I do this or not 

So I was thinking of taking all three of my card in dino and driving them at speed of 40 to 50 for 5 to 10mins after adding fuel stabilizer 

Also tires will get bad and I don't wanna get any chances. So I asked my friend if I can borrow his jack from dealer. So I was gonna put all three of my cars on jack and take wheels off until I come back 

Also I changed battery on both si and spder because they have more mileage as compared to type r which has only 4500.... should I change battery on that one to..I don't wanna waste to much money 

Jack he said he is gonna give those for free as a favor from past
