With our cars being direct injection, this poses some minor concerns that were otherwise not present with port injected motors of the past.
Users have noticed that with lots of city driving, your oil level will read HIGHER then before on the dipstick. This is because the oil is subjected to fuel shear (fuel from the injection system mixed with your engine oil which breaks it down or shears the oil, resulting in less engine protection. This is one reason why your oil should be regularly changed.
Another reason is that since these are DI motors, they are sucseptible to carbon buildup on the intake valves. The less often you change your oil, the more buildup will occur on your intake ports due to the contaminated oil. This is another reason why oil should always be changed on time.
With these two considerations in mind, I recommend changing your oil every 5000 Miles.
In Austrialia, the owners manual recommends the following oil weights:
- 0w20/30 for fuel efficiency, cold weather operation. Ideal for conservative drivers in mild climates
-5w40 (5w30 was not even mentioned!) this oil is essentially the happy medium between too thin or too thick. Good for a variety of weather conditions and driving styles. This is what Ive been using for a while now and the engine runs quieter and smoother then before.
-10w30, 10w40, 10w50. Now I will admit that these oils are too thick for most driving conditions, but those who live in hot climates, especially driving aggressively will want to consider an oil this thick. 10w50 is more reserved for track use however.
Due to the concerns that a DI motor may cause, I recommend a tough oil that is resistant to fuel shear and also has some sort of detergents, like a diesel oil (Part of the reason why Diesel engines need detergents is because of the DI system that is shared with our engine)
Ive used many different oils, and the only two I found that were truly tough and able to provide protection at 4000+ Miles was shell rotella t6 5w40 and Motul, which is an incredibly strong and protective racing oil.
Im looking to see when people change their oil on average and what sort of oil weight is used.
