Q: Oil

asked by on January 19, 2018

Hi, what is the best oil that makes the car engine last longer and prevent cold startup? Also do you think synthetic oil flows faster conventional in a car? Is the Castrol Gtx good because I heard they stick to the parts so it prevents the parts from cold startup is it right? Also in my Honda Odyssey 2010 do you think I should put conventional because it is like 7 year old engine. Also I have 81k miles on my odyssey should I put the oil that says High Mileage or it doesn't matter if I use regular oil? Thanks

Hi Patel. Thanks for asking this question. When it comes to choosing oils, the best oil to use across the board for any vehicle is the one that the manufacturer recommends for that particular vehicle. Inside your owner manual, you’ll find a section that talks about what engine oil to use. If you don’t have one, you can review the PDF file by clicking this link. The important items to follow is the recommended viscosity, grade and SAE rating. In regards to brands, Castrol GTX is an exceptional choice. In fact, it’s what our mobile mechanics use while servicing our customer’s cars. While switching to a synthetic has multiple benefits, cold-weather starting is not one of them. A full synthetic is naturally thicker when the engine is cold than a conventional or synthetic/conventional blend So in theory, using a synthetic of the same viscosity is not really great for cold weather starts. You should probably read this article about the risks of switching to a synthetic oil to learn more. In your application, I would recommend using a semi-synthetic, Castrol GTX SAE 5 W 20. This is already a very thin oil, so it’s best to use this all year.
