Lexus vehicles in which 0w-20 synthetic oil is required have been approved for extended oil change intervals of 10,000-miles/12-months. However, you should continue to check the oil level regularly and top off if needed.
Engines that recommend 5w-20 conventional oil, but allow the optional use of 0w-20 synthetic oil, as per the Owner’s Manual, will continue to require 5,000-mile/6-month (whichever comes first) oil change intervals if the 0w-20 is used.
If the vehicle operation meets the standard criteria for “Special Operating Conditions” such as: driving off-road, on dirt roads, towing a trailer, making repeated short trips under 32˚F, or extensive idling; the engine oil must be replaced at 5,000-mile intervals, regardless of what type of oil is used.
If you do a lot of stop-and-go driving in the city, you will want to choose an oil that has a higher viscosity. This will help your engine run more smoothly and prevent premature wear. For those who do mostly highway driving, a lower viscosity oil is typically best. It can flow more easily at high temperatures and will help keep your engine clean.
The climate in which you live also plays a role in choosing the best oil for your car. If you live in an area with cold winters, you will want to choose an oil that has a higher viscosity. This will help prevent your engine from becoming too thick when it is cold outside. Conversely, if you live in an area with hot summers, you will want to choose an oil with a lower viscosity. This will help your engine run cooler and prevent overheating.
Finally, the age and make of your vehicle should also be taken into consideration when choosing the best engine oil. If you have an older car, you may want to choose an oil with a higher viscosity. This will help protect your engine from wear and tear. However, if you have a newer car, you may want to choose an oil with a lower viscosity. This will help keep your engine clean and prevent build-up over time.
