Hi,
I have a 2007 ES350 that I seldom drive. I have another Lexus ES300 and a Honda and I am retired. The odometer of the 2007 ES350 is only 14,000 miles. I have change the oil myself at 3,258; 8,181; 10,038 and 13,224. I use Castrol synthetic oil 5-30. Am I overdoing the oil change? If the manufacturers says 7,000 miles per oil change, which I don't normally follow and change it every 3,000 miles. What is the max time I have to change oil assuming I put only less than 2,000 miles. Is 12 months OK. Every 4 months irrespective of mileage might be overkill. The cost of oil change doing it myself is only $35.00 and probably 20 minutes of my time. What are your opinions guys.
Here's another issue on oil change. Whenever I remove the filter drain or housing cap the whole filter casing rotates. So I just end up replacing the filter and the big "O" ring. Should I put the filter housing on a vise and remove the housing cap for me to replace the small "O" ring? Is this necessary if there's no oil leak? Your thoughts please.
