Miles Between Oil Change With Synthetic....

[ross3031]

So on my last oil change i switch over to the Royal Purple Synthetic. Just wondering how far everybody else running synthethic oil is going before an oil change. I thought you could go just about double as many miles as with conventional, wanted to check first though before i did....

I use CONKLIN 15W40 full synthetic and go 15,000 miles. I buy a quality filter (Wix) and change it at 7500, then change the filter and all of the oil at 15,000. Some might not agree with me, but thats what CONKLIN recommends...I've had three oil analysis' done and everythings good w/ 222,000. I've used CONKLIN for the past 25,000 or so...

Hope this helps
