Yes, but the timing of your first oil change will depend largely on the quality of the rebuild. Due to the tighter tolerances and improved machining of today’s engines, the traditional concept of ‘engine break-in’ is not as critical. However, if the engine rebuilder is using older machining equipment or lower-quality components, abrasive material can be left inside the engine. In this case, you should use a short drain interval on your initial oil fill.

Imperial Oil does not recommend it. According to the American Petroleum Institute (API) and Alliance of Automobile Manufacturers (AAM), “certified oils eliminate the need for supplemental engine-oil additives.” In fact, the use of any oil supplement is not recommended by car manufacturers and may void a warranty. Considering the comprehensive testing and engineering that has gone into Mobil 1, nothing can be gained by using these supplements. See similar questions...

Mobil 1 Extended Performance contains an extra performance additive to help deliver exceptional performance and protection. This fully synthetic technology is designed specifically for longer service intervals. Appropriate viscosities of Mobil 1 Extended Performance also meet all the requirements for GF-4. Additionally, they exceed the requirements of API SL/CF and various ACEA (European) specifications. (Updated March 2006) See similar questions...

Yes, it is. To meet the demanding requirements of today's specifications (and our customers' expectations), Mobil 1 with SuperSyn uses high-performance fluids, including polyalphaolefins (PAOs), along with a proprietary system of additives. Each Mobil 1 with SuperSyn viscosity grade uses a unique combination of synthetic fluids and selected additives in order to tailor the viscosity grade to its specific application.

These claims relate to all typical consumer driving conditions, excluding those mentioned below. In other words, if you drive under normal conditions and use Mobil 1 Extended Performance in your vehicle, the oil is guaranteed to protect your engine for 15,000 miles. We also recommend that drivers consult their owner’s manual while their vehicle is under warranty, and follow the guidelines set forth there. See similar questions...

While Imperial Oil recommends that you use a high-quality filter, you can use the same type of oil filter that you would normally use with conventional oil. See similar questions...

Mobil 1 Extended Performance formulas are designed specifically for today's longer service intervals and are guaranteed to protect for up to 15,000 miles or one year. Mobil 1 Extended Performance has a unique formulation with a boosted level of protection and performance. Mobil 1 Extended Performance, with the Advanced SuperSyn System, contains 50 percent more SuperSyn than Mobil 1. See similar questions...

First, let's be clear about Mobil 1's overall benefits compared to those of conventional motor oils, whether for passenger cars or motorcycles: It's a little hard to generalize about the difference between Mobil 1 passenger-car motor oils and Mobil 1 motorcycle oils. That's because not all viscosities of Mobil 1 passenger-car oils have the same levels of zinc and phosphorus, and there are even greater differences among the three Mobil 1 motorcycle oils.

Any engine oil can be used as long as it meets the specifications listed in the engine manufacturer's manual. In addition to flushing your engine after your boat has been exposed to salt water: clean, wash, and dry all exposed metal parts and coat them with a preservative such as WD40. This will prolong the life of the exposed metal parts. See similar questions...

AVBLEND keeps friction surfaces cool during break-in period. One of the most important functions performed by AVBLEND is its ability to keep friction surfaces relatively cool while the metal is new -- during the break-in period. Too much heat during this critical period while the metal is forming itself into its job can easily cause brittleness, loss of flexibility and a tendency to break under sudden and severe strains.

Mobil 1 with SuperSyn Technology exceeds the latest industry and OEM requirements. It is designed for vehicles under warranty and will provide protection for the maximum oil change interval recommended in your owner's manual or by your oil life sensor. The overall goal for Mobil 1 has always been to protect your engine, even under the most severe conditions, such as cold starting temperatures, extreme high-temperature operations and high-load conditions.

Mobil 1 Racing 2T was discontinued in the fall of 2007, and there is no replacement for it in the Mobil 1 motorcycle oil product lineup. See similar questions...

In addition to the overall benefits listed above – specifically, high-temperature stability and low volatility/low oil consumption – Mobil 1 synthetic motorcycle oils also offer superior anti-corrosion performance compared to conventional motor oil, which is important in many parts of the country where bikes may sit in garages for several months of the year.

Mobil 1 is fully compatible with conventional motor oils, semi-synthetic motor oils and other synthetic motor oils, should it be necessary to mix them. But the superior performance of Mobil 1 will be reduced by diluting it. You can, but Imperial Oil does not recommend this practice. You give up much of the superior-performance characteristics of Mobil 1. The conventional oil in the mix will adversely affect the low-temperature flowability and high-temperature oxidation stability of Mobil 1. See similar questions...

Absolutely not. No special preparation is necessary when switching from conventional motor oil to Mobil 1. See similar questions...

Mobil 1 Racing 4T 10W-40 is designed for sport bikes. Most of these bikes have multi-cylinder/multi-valve engines and use a common sump, which means the engine oil lubricates the engine, transmission and wet clutch. So unlike Mobil 1 for cars, Mobil 1 Racing 4T 10W-40 has no friction modifiers, which could lead to clutch slippage. The motorcycle oil also has more phosphorus/zinc for enhanced wear protection at high engine speeds and high loads. See similar questions...

There are no new G-13 engines (but there are plenty of used blocks available).  As all race engine builders know, a seasoned (used) block is much more desirable because the block is cooked in and proven. See similar questions...

If an API CF or CD oil is recommended for your diesel engine, Mobil Clean 5000 is an excellent choice. If your vehicle calls for an API CI-4 oil, Mobil 1 Turbo Diesel Truck 5W-40 is an excellent choice. (Updated March 2006) See similar questions...
