Synthetic oils, intended for more modern vehicles and engines, are by far the best choice as they are different from mineral and semi-synthetic oils in the specific processing methods, characterized by excellent resistance in extremely low and high temperatures and protective of engine wear. One of the frequent oil markings in cars is SAE 5W The goal of a motor oil is to protect the vehicle engine in winter when the temperatures are low or that the oil is light enough to run the engine without any difficulties in cold start, and it is sufficiently dense to keep the engine running at the same operating temperature. The aim is to reduce the viscosity of the oil at low temperatures, and to increase at high. This allows use of the same oil throughout the year. Oils that meet only summer or winter conditions are called single or mono-grade oils. In order to obtain multi-grade, i.

Remember Me? Private First Class. Looking to buy an fcp euro oil change kit, but torn as to weather to do the 5w or 5w luqi moly. I think I want to stick to the oem 5w but have heard of lots of people running 5w, what would be the benefits of it? Thanks for any advice. Appreciate 0. Lieutenant Colonel. Dare I say the engine felt slipperier. A weird way to put it, but I know my ride, and that is the best way I can describe it. Much smoother. I live in Texas. I have an oil cooler with a cheater thermostat. I see no need for 5w Now if that Blackstone comes back clean I'll be one happy camper.

And when it is about the lubrication of engine parts, avoiding the important terms will not be a wise option. If 5w30 oil fulfills in some conditions, 5w40 lacks there and the same goes for the other. Where 5w30 oil works best in low temperatures, 5w40 oil outperforms in high temperatures. In similarity, 5w40 contains more viscosity compared to 5w30 and grants more thickness. And talking about the quality, none of them is less than each other. So what makes them different? And which one can be your better alternative to choose? If you want to pick your oil that matches with your conveniences then have a look at my article.

Are you planning on flushing your motor oil and you are confused by the numbers 5w30 vs 5w40 and you are thinking of which oil you should pour inside of your engine? Why is this the case? This is the case because every oil works differently.

From the research I've done recently it seems like the oil has fallen out of favor due to them no longer including those additives. Appreciate 1. So either a 5w30 or 5w40 would be fine, the latter may provide a bit more protection hence why allot of tuners may opt for it as people who tune their cars are more likely to push them harder.. Many manufacturers test their cars for quality on special booths. Photo: THMotorsports The 5w40 is crude-based motor oil that is best fit for diesel and gasoline engines. However non of them is 5w Its main advantage is to protect and keep the engine parts in the best condition and operate smoothly. It seems like an expensive job.
