Which weight would you recommend for a 2000 Dodge Stratus?I am thinking since it has 200,000 miles, and likely has some wear, Mobil 1 0w-40 would be a good choice. I am thinking it would get to the engine quickly when cold, and will also be thick enough when hot to hold good oil pressure. The owners manual says 5w-30 for below 38 degrees and 10w-30 for above -18 degrees. I am a believer in using what the engineers said to, they likely know their engines better than I do. However, using synthetic 10w-30, the oil pressure light stays on for 5 or so seconds after a cold start. Scary. I am thinking if I use an oil that is thinner when cold, it will reach the engine quicker and if thicker hot when hot, it will hold oil pressure well. What would you use? I am thinking Mobil 1 European 0w-40. What do you think?
