I am a great believer in regular (3,000 miles) oil and filter changes. My oldest sister bought herself a brand new Toyota Supra, when Toyota claimed that you didn´t need to shange out the oil and filter but every 7,000 miles. I told her to ignore that recommendation and change it at 3,000 miles. Her then husband told her she only needed to change it like Toyota recommended.
The kid that changed her oil every 7,000 miles, told he she should change it sooner, because the oil was coming out like thick molasses. She ignored him, thinking he was just trying to sell her more oil. The long and short of the story is, that my sister had to have the engine completely changed after only three years, at the cost of $2,800, which at that time was a lot more money than now, because the engine was completely worn out, TRASH!
These car manufacturers have a vested interest in us not maintaining the cars as we should, because then we will need another car sooner. They aslo want to make you think you can save money on maintainance if we buy their produce, versus any other car that needs to have the oil and filter changed sooner.
You can do like the add used to say. You can pay me now or you can pay me later.
