When it comes to engine oil everyone has a preference or anecdotal evidence why one oil is better than another. Engines that have higher mileage or have started to "burn oil" ,I would have no problems recommending a higher viscosity oil perhaps 20/5/0 thicker oil should give adequate protection and "burn" less oil. The key to long engine life is frequent oil changes!
