Just go with any good high mileage type 10-30 oil and a decent filter. Purolators are good and cheap too. The high mileage oils will slightly swell the oil seals and prevent leakage. You probably need new seals on the timing belt side of the engine anyway. Pennzoil Hi mileage and Purolator filters have gotten my 97 camry to 205,000 miles. I fully expect to get 300,000 miles from the car.
