Cars need engine oil to operate smoothly and it also helps in keeping the vehicle’s parts lubricated, in moving condition while protects against corrosion. With all the latest detergents to the oil additives, your car is free from the usual engine gunk and sludge. Still, there’re also things about engine oil being incorrect such as changing oil after every 3,000 miles.
What if the oil starts turning dark, isn’t that a clue of harmful sludge filling your engine. Well, it’s true there’re myths surrounding the concept so we’ll debunk them through the facts mentioned here so do consider giving them a look that can save you a lot of unnecessary expense.
- 10W-30 oil: “W” is the “weight”
When buying engine oil, it’s important to know about the viscosity; thickness. The less the viscous drag, more smoothly it’ll slide through the engine and lubricated the moving parts. Some of the best motor oils have a balanced thickness that is neither too high and nor too low. Viscosity can be measured in two ways namely; single and multi-grade.
SAE 30 here represents single-grade rating whereby the acronym for “SAE” is for Society of Automotive Engineers. It’s responsible for testing the oil through a standardised tube-like device to check the drag or thickness. Total time in which oil would slide from one end to another would determine the viscosity rating which is the number of seconds rounded up-to-the nearest ten multipliers. So the very term SAE 30 defines 30 seconds time.
This thickness of oil also changes with the temperature so what should you expect when starting the car in cold winter morning; obviously slow movement of oil. Multi-grade rating defines both hot and cold viscosities.
- Darker tone of the oil
Unless you’re too much conscious about keeping the car in good order, dirty and sludge-like oil may give you a splitting headache. If the oil turned amber and depositing sludge, it’s bad right! Wrong, in fact, the opposite is true. If you’re using detergent engine oil as some of the most modern ones have such additives, its work just perfectly. The tiny particles actually keep the engine and suspension system operational. Rather than changing the oil simply because of the colour, follow the recommendations from the vehicle manufacturer.
- Necessary replacement after every 3,000 miles
There was a time when almost every other auto manufacturer suggested changing the car oil once the vehicle’s mileage reaches 3,000. This is no longer true as modern detergent-based oils improve viscosity and allow better performance of the vehicle. The mileage count effective nowadays is 7,500 miles after which you may consider changing it. Many sellers still emphasise on the past fact which is just a trick to hoard more money and sell you the oil brand.
- Additives for better performance
Well, that’s true but “additives” are already present in the oil before you even buy it and a process that’s carried during production. Any reputable brand surely contains the right viscosity and extracts for a tuned engine, keeping it sludge-free. Most brands also contain rust retardants and chemicals to protect metallic surfaces. You should carefully read the vehicle’s manual to see if any special additives are needed.
- Synthetic oils causing leaks
Back in the early 70s, synthetic engine oils became popular containing chemicals such as poly alpha olefins. However, they reduce the sealants and making quite a messy leak which is something that doesn’t happen with petroleum-based oils. People even fear the same today however it no longer happens as producers learned a long time ago about this particular dilemma and reformulate the lubricant.
However, if you’ve an older vehicle or even the latest model which lacks crucial maintenance, synthetic oils can cause a leak. Synthetic oils cleanse the oil sludge off the seal that might’ve been blocking tiny cracks; leaks will be revealed that were there in the first place.
A car that’s probably more than 15 years old may face such issues but the built tends to vary with each model so you should always consult the manufacturer or a reliable auto service provider.
