Synthetic Oil

Synthetic and synthetic blend motor oils are designed to be the highest quality motor oil available for your vehicle, for when you want the best protection and performance possible.

What is synthetic motor oil? Simply put, synthetic motor oil is specifically created from chemical compounds. These formulations allow scientists to create motor oil that at a molecular level is able to provide superior, more complete protection for your engine than conventional oils can. This means a series of complicated-sounding but significant benefits, like less evaporative loss, a higher viscosity index, greater resistance to oxidation thermal breakdown and sludge problems. Plus, markedly superior low and high temperature performance. Bottom line: synthetic oil helps keep your engine as close to new as possible for as long as possible, which adds up to you having greater peace of mind on the road.

There are many reasons people decide to use synthetic oil. First, because your vehicle’s manufacturer requires it. More and more manufacturers today design their engines specifically around the superior protection and performance properties of synthetic oils. Your Jiffy Lube® technician can tell you which oil is required for your vehicle, or you can look at your vehicle manufacturer’s recommendations. You may risk engine damage if you don’t use synthetic oil, and you may void your new-vehicle warranty.

The second reason to use synthetic oil is because it offers better protection and performance, regardless of whether your manufacturer requires it or not, particularly in extreme temperatures. Synthetic oil flows more freely at freezing temperatures than conventional oil and resists breakdown or “burn off” at higher temperatures. The difference is really eye-opening. So especially if you live in areas of the country where temperatures sometimes get down to single digits and/or climbs near or exceeds triple digits, you should consider a synthetic or synthetic blend. You should also consider a synthetic or synthetic blend if you do a lot of towing or other “severe use” driving, like lots of stop-and-go traffic or grinding, rush-hour, big-city commutes.

Jiffy Lube® recommends following manufacturer recommendations, where applicable, for maintenance schedules and service intervals.

Is synthetic oil a lubricant? ›

Synthetic oil is a man-made lubricant that consists of artificially made chemical compounds. Synthetic oils are typically created from chemically modified materials such as petroleum components, but the base material is almost always distilled crude oil.

What is one problem with synthetic oil as an engine lubricant? ›

Synthetics may be more prone to additives precipitation during cold storage conditions. This stratifies certain additives which can potentially lead to their complete separation from the oil. Multi-grade motor oils using synthetics may exhibit slightly less fuel economy at highway speeds compared to mineral oil.

When should you not use synthetic oil? ›

Better For Older Engines

This being said, however, it is still not recommended to use synthetic oil in engines that have experienced significant actions – specifically, those that have reached around 75,000 miles on the odometer.

Does synthetic oil lubricate better than conventional oil? ›

Due to the additives and uniform molecular structure, synthetic oil lubricates better, flows better, is less prone to oxidation, and is more stable than conventional oil. 2. Engine Wear: Regular oil can have tiny unwanted bits that can accumulate over time and create deposits in the engine if you don't change it often.

What are the disadvantages of synthetic lubricants? ›

Disadvantages of synthetic oil

Multi-grade motor oils using synthetics may exhibit slightly less fuel economy at highway speeds compared to mineral oil. The oil could leak out of old engines with loose seals and gaskets. This is due to lower pour pont and flowing characteristics even at low temperatures.

Why can't you go back to regular oil after synthetic? ›

Myth: Once you switch to synthetic oil, you can never switch back. This is one of the most persistent myths about synthetic oil—and completely untrue. You can switch back and forth at any time. In fact, synthetic blends are simply a mixture of synthetic and conventional oils.

Is it okay to mix regular oil with synthetic oil? ›

Can You Mix Conventional Oil With Synthetic? The short answer is yes. There is no danger or risk of combustion, and mixing the two types of oil won't harm your engine. However, it's important to note that if you do mix the two, the conventional oil can keep the synthetic from performing to its fullest potential.

Do engines last longer with synthetic oil? ›

Synthetics have some advantages over conventional motor oil. They're designed to be more effective at: Resisting oil breakdown, which makes it last longer than conventional oil. Withstanding higher temperatures than conventional oil, which helps keep engines running longer.

Do cars run better with synthetic oil? ›

5. Is synthetic oil better for my engine than conventional oil? Yes, synthetic oil is better for your engine than conventional oil. Although conventional oil (i.e., mineral oil) can provide adequate lubrication performance, it can't compete with the overall engine performance and protection provided by synthetics.

Will synthetic oil hurt older engines? ›

Use Ester-Free Synthetic Oil

Since esters cause issues for the engines of older vehicles, choose a synthetic oil product that doesn't use these harmful chemicals. Today's synthetic oil products are ester-free. They use different compounds that don't attack the engine seals.

At what mileage I should stop using synthetic oil? ›

Most new cars use synthetic oil. That means you typically only need to change it at the 7,500-mile mark, or even wait until 10,000 miles. Some cars are even rated at 15,000 miles between changes.

Will synthetic oil damage a high mileage engine? ›

Those who decide to switch to high-mileage synthetic oil may face leakage problems due to the potential incompatibility of the synthetic used in certain oils with the engine's seal types.

How often do you change synthetic oil? ›

It's recommended that you change synthetic oil every 7,500 – 15,000 miles, depending on the vehicle and the brand of synthetic oil used. To ensure you're changing your oil at the proper intervals, always check your owners manual for more information.

What oil is better than Mobil 1? ›

AMSOIL synthetic motor oil uses naturally shear-resistant base oils combined with top-tier, shear-stable viscosity improvers that withstand extreme heat and shearing forces. Not only does AMSOIL exceed industry standards and outperform competing brands, it fights viscosity breakdown 46% better than Mobil 1.

Does synthetic oil require a special filter? ›

You will want to check with your vehicle's manufacturer to make sure, but typically any automotive filters that are made for modern vehicles can be used with any type of oil. Every major motor oil manufacturer says you do not need a special or different oil filter when using synthetic oil.

What type of oil is lubricant? ›

There are two basic categories of lubricating oil: mineral and synthetic. Mineral oils are lubricating oils refined from naturally occurring crude oil. Synthetic oils are lubricating oils that are manufactured.

What is considered lubricating oil? ›

Lubricating oils are composed of 80–90% petroleum hydrocarbon distillate with 10–20% additives to impart specific properties to the oil. The petroleum hydrocarbon distillate generally consists of paraffinic or naphthenic compounds, whose properties are listed in Table 1. Measure of stability/chemical breakdown.

What is the purpose of synthetic oil? ›

Synthetic oil is used as a substitute for lubricant refined from petroleum when operating in extreme temperatures because, generally speaking, it provides superior mechanical and chemical properties to those found in traditional mineral oils.
