Liqui moly 5w30 vs 5w40

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. These additives will reduce viscosity in cold engine operation, but also increase viscosity at engine running temperatures. This product belongs to the category of universal lubricant oils and therefore has a great set of qualities. Many manufacturers test their cars for quality on special booths. But anyway, the characteristics that the manufacturer puts on the packaging can be significantly different from those that the substance will have during intensive work on the internal combustion engine. In these regards, car dealers, as well as motorists, conduct their own oil test in working conditions. The tests are designed to show over which period of time the product loses its traits. To achieve a more economical ride, US engineers have introduced a number of parameters that give the right combination of certain SAE 5w40 viscosity oils to lead to energy savings. It is imperative to reduce oil consumption by 1.

As we compared above, you also see that the 5w is superior, although sometimes, the price is a bit high. I have not measured any other changes.

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.

Is it common? Conclusion: the cam failures has to do with cam roughness. If we compare the cost of both these motor oils, 5w30 is comparatively more than that of 5w It looks like what I got last time was VW as shown in the attached image. Is there evidence one way or the other in places like Poland? I don't worry about using oil that doesn't have that rating. In general, 5w30 is a great multi-grade oil for different temperature specters. Although I have miles to go before the mileage my mechanic mentioned to change the engine oil, I will be changing engine oil next week since I have not changed it for almost a year. Out of which 5w30 and 5w40 are the most preferred choice of the people out here. Come join the discussion about M performance, turbo kits, engine swaps, builds, modifications, classifieds, troubleshooting, maintenance, and more! Is there any advantage to 5W40 in terms of reducing wear, sludge or oil consumption or should I just stick with 5W30? I live in Texas.

Haven't had any issues so far. Well you can't answer that until you nail down a possible other variable. For a better experience, please enable JavaScript in your browser before proceeding.

The V6 would often burn oil on older engines, especially on the highway. I guaranty you can not defeat this theory. I was always curious if I should ask for 5W as the manual mentioned. In order to obtain multi-grade, i.
