20/50 would be WAY too heavy, maybe if you lived in death valley or something it would be ok. but ya it would suck. if it doesnt leak or seeps jus a lil bit i use 10/30 if it leaks i use 10/40 to slow it down
20/50 is the only thing keeping my truck from going through 3-4 quarts of oil a week... but yeah anything that was properly maintained before being purchased should be 10/30 stuffs.
I use GTX 10w - 30 in the winter ( barely drive anymore with it bagged ) & I use 10W - 40 in the summer and I always use Marvel Mystery oil with all oil changes and fuel ups (" Great stuff " . . .
10w-30 in the winter and yes i do indorse the good ol 20w-50 the rest of the year keeps nice and lubed but btw watchout on those nice early mourning starts gotta let it get get away from that honey state and get to the oil state lol i dont care what you all say i love my 20-50
if i did that...i would be late for work..hahaha I use 20-50 in the dog days o summer, and 10-30 the rest. Its does get 100-110 here for 2-3 months. That's why ill NEVER delete my A/C.100 degrees and 90% humidity will choke you smooth out.
