Just bought a 93 yj with a 4.0L that has been setting for 3 years (busted d35). The oil has really bad carbon grit in it. I have talked to 2 different mechanics that said to drain the oil and fill the engine with kerosene (about a gallon) and let it idle for 45 seconds drain and repeat once more. After this, run a high detergent oil for 1k miles and chage again. Sounds risky with the kerosene...any input?
