I tried synthetic blend and got some minor pan leaks, so went back to conventional. Tried full synthetic too.
Synthetic is overrated IMO. Good for new cars, but older car over 10 years old do just as well on conventional.
We've had three brand new cars in the last 15 years. Two Toyotas and one GMC Jimmy. We had a two year old Cadillac with the so called great "split block"! It leaked a little oil too.
Our 2005 4runner would leak on synthetic oil.
Hardly any (no leaks) with conventional, so I run conventional.
you should change the oil either way every 5000 miles IMO.
Oil gets dirty and properties deteriorate.
Scotty Kilmer says the same thing about synthetic in older cars. Watch out for the leaks!
