Normally the oil pressure on my 2000 Wrangler Sahara (83,000 miles) is steady at 40 psi. Lately, it has been dropping to as low as 20 psi and staying there (after 5-10 minutes of warm-up). I routinely change the oil every 3,000 miles. The oil level is good.
What is the normal oil pressure range?
My friend suggests a problem with my bearings??? That sounds expensive.
Any insight, advice, information would be appreciated.
