I have a 2005 Toyota Camry and I just put in the following into it.
Oil - Royal Purple 51530 API-Licensed SAE 5W-30 High Performance Synthetic Motor Oil - 5 qt.
Filter - Royal Purple 10-2840 Extended Life Premium Oil Filter
On the Royal Purple website (http://www.royalpurple.com/consumer/why-synthetics/) it states “Nowadays, many carmakers commonly recommend an oil change interval of 5,000 to 7,500 miles, or sometimes even 10,000 miles or more, under ideal operating conditions. Certain premium products like Royal Purple API-licensed synthetic engine oils allow motorists to travel as many as 12,000 miles as the recommended oil change interval. Even more amazing, Royal Purple HPS™ synthetic performance upgrade street oils allow up to 15,000 miles in between motor oil changes.”
So I can go 12,000 miles or 15,000 miles within a year before I need to change it? Also on the amazon product page for the oil I put in it states the following:
“Can Royal Purple Motor Oil Be Used In Older Engines?
Yes. Mileage and/or age is not a factor when used in a mechanically sound engine. In high-mileage applications, it’s recommended running a minimum of two short (3,000 mile/5,000Km) intervals before extending the oil drain intervals. This will enable Royal Purple’s high solvency to remove existing deposits gradually; such deposits can restrict oil flow, if excessive, as well as reduce the oil service life significantly.”
Is it really necessary to do two 3,000 mile oil changes when switching over to Royal Purple? I have had used synthetic oils in the past, just never royal purple. I have just over 155k miles on my car.
