What type of oil are you using? synthetic or conventional.
True story: I switched to synthetic after 11 years of conventional in my 2005 V6 4runner with 160,000 miles. This was a "try-out"! Immediately I got oil drips on the garage floor, so I drained it and put NAPA conventional 5W 30 back in.
Immediately the oil drips slowed down. After 6 months they were down to three drips a month. Now, I'm down to one drip a month.
Synthetic is overrated IMO. In my car where I change the oil every 5000 miles conventional is better.
