Bought it for 1200 first picture is at idle second is at 3000 rpm’s and I just changed the oil and put a quart of Lucas in with it and used 10w30 instead of 5. Has 323000 miles on it and if I don’t put Lucas in it it gets about 10ish to 15 pounds instead of 20 has a new sending unit. Should I just run thicker oil in it next oil change or just keep going this route and just drive the wheels off of it because it has so many miles?
