• Mobil 1 5W-30 is a high-performance motor oil for all types of cars where this viscosity is recommended. Up to 20,000 miles of outstanding wear protection for high mileage vehicles – guaranteed. We put our Mobil 1™ motor oils to the test in the lab, Castrol GTX on the road and on the track – duplicating some of the toughest, most extreme, real-life conditions anywhere in the world. It’s hard to give a specific time or mileage figure because the life of a filter depends on how much debris it ingests.
The new ILSAC GF-6 standard for engine oils improves your vehicle’s fuel economy and engine performance. We’ve met and exceeded the standards with many of our Mobil™ motor oils. Mobil 1 advanced full-synthetic motor oil 5W-30 utilizes Mobil 1’s signature Triple Action Formula to deliver outstanding engine performance, protection, and cleanliness. Mobil 1 High Mileage 5W-20 motor oil helps extend engine life and prevent leaks in vehicles with more than 75,000 miles.
The second number indicates how well the oil flows in hotter temperatures. The higher the number, the better the oil flows in warm temperatures. A Take 5 technician will help you identify the correct viscosity based on your vehicle’s manufacturer requirements and individual needs. Full synthetic motor oils typically outperform synthetic blend and conventional motor oils and can enhance the protection and performance of your vehicle.
Contaminants are whipped into oil as it runs through your engine. Neglected oil will eventually turn these contaminants into sludge. Contaminants such as unburned moisture and fuels reduce the effectiveness of the oil additive package and cause the oil to get dirty, typically between 3,000 and 5,000 miles. For those who typically Castrol GTX drive over 5,000 miles between oil change intervals, synthetic oil is the best oil for your driving needs. The vehicle manufacturer’s recommendations address driving habits and conditions to determine the most responsible drain interval for you to follow. It is strongly recommended that you consult your vehicle owner’s manual.
The result is a hydrocracked, hydroisomerized conventional oil. Lubes N’ Greases magazine has reported shortcomings in the ability to pass the tests that the original Mobil 1 formula was able to. The brand range now includes a variety of engine oils, oil filters, chassis grease, transmission fluids, and gear lubricants. I’ve used Mobile 1 oils exclusively in my performance cars and daily drivers for years. It always comes out as clean as it went in, and never have had an issue with sludge.
Eventually every filter reaches some point where it causes enough of a pressure drop to restrict airflow. Fuel economy, performance and emissions begin to deteriorate and get progressively worse until the dirty filter is replaced. So inspection at the same time you change your oil would be a good practice. I’ve had my 1998 Ford F150 with a 4.6L SOHC V-8 since new. Crank and cam journals were void of wear and we went back with standard sized bearings.

Keep them on the road with Mobil 1™ High Mileage synthetic motor oil. In 1998, Mobil sued Castrol over the discovery that Castrol was processing conventional oil and calling it synthetic. At the time, Mobil 1 was still created using a true synthetic basestock, which is more expensive. Mobil lost the lawsuit, and, as a result, the definition of ‘synthetic oil’ became looser. In response, Mobil downgraded their process to the less expensive process.
