This is question for Eric since he is Honda/Acura expert.
I have one 92 Acura Integra with 240K mile already. I usually do my oil change every 3-4K miles, for 15+ years. Before, I can get about 3 qt old oil when I do oil change. Now, I discovered I need to add 3/4 qt at 2K mark. By the time I do my oil changes at 3-4k, I would still get about 3 qt oil left. In other word, my 92 integra is burning about 1.75 qt oil for 4K mile. I fixed oil leak thru one of overhead cam shaft, and could not find oil leak thru engine block. Engine still runs good.
I noticed this model of car does not have EGR valve, and exhaust gas is directly feed into air intake. Is this why is burning some oil? Do you recommend using thicker oil like 20-50 for this old car?
Thanks.

I’m not Eric or an expert but are you sure your burning oil and not leaking? If it’s burning rule of thumb, black or blue smoke. Have you replaced piston rings and valve seals throughout the 240k? Sounds like it’s about time.
I would not switch to thicker oil. With the mileage
on the motor. Keep adding the oil. Terrible getting old.Adding 3/4 qt every 2k miles is not a big deal. Top off the oil and keep driving. There are a lot of people out there who have to add much more oil more often than that.
Exhaust is not routed directly into the intake. The B series engine did not have an EGR with a manual transmission. It was not required to meet emissions standards.
Those engines burn oil new. You have quite a few miles on there. It’s likely you’re do for a replacement or a rebuild of the engine. Remove the plugs. If you see brown soot on them, you’re burning oil. Thicker oil will not fix this. Magic in a can will not fix this. Worn out parts need to be repaired or replaced.
Good luck.
