QUESTION ABOUT OIL TO USE!

[tamdo714]

i want to get an oil change and want to gradually move to full synthetic so i'll change it to synthetic blend now. what oil weight should i be using for synthetic blend and what brand? thanks! i tried searching but too much to look at. i drive a 89' 240 stock ka thanks again

don't make a difference. go full syn, just watch out for oil leaks. it'll start cleaning up the insides and you'll find where you've got leaking seals and stuff. Mobil 1 10w-30 is an excellent choice for the SOHC.
