What is the oil change interval?
It is the amount of miles you can drive before changing your oil and it’s essential to learn about the correct interval for a synthetic oil change interval for cars. Initially, the standard oil change interval was at 3,000 miles. However, today we have products that can offer protection far longer than that. So if you are asking “how many miles can i go between oil changes with synthetic oil?” then see the sample graph below.

Currently, only Amsoil Signature Series can boast about a change interval of 25,000 miles. In most cases, people tend to extend the oil change intervals when using the synthetic oil types, it’s advisable that one upgrades to a premium oil filter which is designed specifically for synthetic oils. With such a filter, you are sure that it can withstand the long oil change intervals and contain the impurities effectively.
Here is an excellent article on oil change intervals.
What is synthetic oil made of?
The synthetic lubricant is an artificially made oil that contains chemical compounds such as altered petroleum. Synthetic lubricants are usually manufactured in a lab via certain chemical components and/or raw materials which is a bit different compared to crude oil.
This was majorly inspired by the jet engine invention. These products majorly consist of polyalphaolefins (PAO) and other esters. It actually possesses most of the qualities similar to crude oil.
Synthetic Oil vs. Conventional Oil?
There is a very distinct difference between synthetic and conventional oil. In that case, as a car owner, there is the need to know the type of oil that works best for your car. If you would like to get the difference between the two, here is a distinct comparison. Synthetic oil is a more refined oil than the conventional oil type. This is because synthetic oil is put through an additional process that makes it more refined.
This involves processes like purification, a distillation that helps to take out the individual impurities that may be found in the oil. In addition to that, these processes help to tailor the molecules found in this oil to suit the nature of modern engines. For that reason, synthetic oil helps your engine to resist high temperatures, it enhances cleanliness as well as durability of the engine.
Full Synthetic Oil vs. Synthetic blend?
When it comes to motor oils especially, they have never been created the same way. There is always some distinct characteristic in each one of them. Before we proceed, I bet you already know the difference between the synthetic and conventional oils. Well, as this may come as a bit obvious to most of us, the synthetic type has further categories. We have full synthetic oils and synthetic blends. Well, if you are wondering how the two are different, we will explain below.
1. Ingredients; while the full synthetic oils may contain fully man-made base oil with synthetic chemical compounds the synthetic blend, on the other hand, consists of mineral oil blends and a synthetic base oil that contains a mixture of the synthetic oil compounds as well as a mixture of crude oil.
2. Performance; the full synthetic oil is made through a synthesis process which improves the attributes and key performance of this oil. In that case, it increases the protection of your engine to wear, extreme temperatures as well as deposit control.
3. Cost; is no contest at all when it comes to cost difference between the two. The full synthetic oils definitely cost a few bucks more than the synthetic blend but they will have longer drain intervals.
Synthetic Oil vs. Conventional Oils for Older Cars
A question commonly asked is which oil to use for an older vehicle (definition of older vehicle is a vehicle made before 1990). There is a common myth that synthetic oils are not the ideal selection for older cars. All in all, thinking about the situation critically, synthetic oils will actually help to lubricate and protect old engines just like synthetic oil protects new engines. On the other hand, the seals might not be as tight and you may experience a leak. Synthetic oils can prolong the life of an older engine, but before making the switch, you should consult with your local friendly mechanic who will inspect your vehicle and inform you on the process for switching to a synthetic.
