Question 1

How often should I change AMSOIL synthetic oil?

Accepted Answer

AMSOIL Signature Series synthetic motor oil is engineered for extended drain intervals of up to 25,000 miles or one year, whichever comes first. AMSOIL XL Extended Life synthetic oil offers up to 10,000 miles or six months, whichever comes first. AMSOIL OE synthetic oil follows your vehicle manufacturer's recommended drain interval. Always consult your vehicle's owner manual and consider your driving conditions when determining oil change intervals.

Question 2

Is AMSOIL really better than conventional oil?

Accepted Answer

Yes, AMSOIL synthetic oil provides superior protection compared to conventional motor oil. Synthetic oil molecules are uniform in size and shape, providing better lubrication, superior high-temperature stability, improved cold-weather performance, and enhanced resistance to oxidation and thermal breakdown. AMSOIL products undergo rigorous testing and consistently outperform conventional oils in industry-standard tests for wear protection, deposit control, and thermal stability.

Question 3

Can I switch from conventional oil to AMSOIL synthetic oil?

Accepted Answer

Absolutely. You can switch from conventional oil to AMSOIL synthetic oil at any time without flushing your engine. AMSOIL synthetic oils are fully compatible with conventional oils. When making the switch, simply drain your conventional oil at your next scheduled oil change and refill with AMSOIL. The superior cleaning properties of AMSOIL will gradually remove deposits left by conventional oil, improving engine performance over time.

Question 4

Will using AMSOIL void my vehicle warranty?

Accepted Answer

No. Using AMSOIL synthetic oil will not void your vehicle warranty. Federal law (the Magnuson-Moss Warranty Act) prohibits vehicle manufacturers from voiding warranties simply because you use a different brand of oil, as long as the oil meets the required specifications. All AMSOIL motor oils meet or exceed the latest industry specifications and OEM requirements, ensuring full warranty protection.

Question 5

How much does AMSOIL cost compared to conventional oil?

Accepted Answer

AMSOIL synthetic oil has a higher upfront cost per quart than conventional oil, typically ranging from $10 to $14 per quart depending on the product line. However, when you factor in extended drain intervals (up to 25,000 miles or one year, whichever comes first, for Signature Series versus 3,000-5,000 miles for conventional oil), AMSOIL actually costs less over time. Most users save $200 to $1,000 over five years compared to conventional oil when accounting for fewer oil changes, filters, and labor costs.

Question 6

What is the AMSOIL Preferred Customer program?

Accepted Answer

The AMSOIL Preferred Customer program offers wholesale pricing on all AMSOIL products, typically saving up to 25% compared to retail prices. The annual membership fee is modest and pays for itself with just one or two product purchases. Preferred Customers also receive free shipping on orders over $100, exclusive promotions, and access to the full AMSOIL product line. It's the most cost-effective way to purchase AMSOIL products for regular users.

Question 7

Which AMSOIL product is right for my vehicle?

Accepted Answer

AMSOIL offers three main motor oil lines: Signature Series (premium protection, 25,000-mile drain intervals), XL Extended Life (excellent protection, 10,000-mile drain intervals), and OE (OEM-quality protection at manufacturer drain intervals). The best choice depends on your driving habits, vehicle type, and budget. Use the AMSOIL Product Lookup Guide on their website to find products specifically formulated for your vehicle's make, model, and year.

Question 8

Does AMSOIL improve fuel economy?

Accepted Answer

Yes, many AMSOIL users report improved fuel economy after switching from conventional oil. AMSOIL synthetic oils have lower friction coefficients than conventional oils, reducing internal engine resistance and improving efficiency. Independent testing shows fuel economy improvements of 1-3% are common, though results vary by vehicle, driving conditions, and maintenance history. Over time, these small gains add up to meaningful fuel cost savings.

Question 9

Can I use AMSOIL in my diesel truck?

Accepted Answer

Absolutely. AMSOIL offers specialized diesel motor oils engineered for the extreme demands of diesel engines. AMSOIL Signature Series Max-Duty Synthetic Diesel Oil provides maximum protection for heavy-duty diesel trucks, offering superior wear protection, excellent soot control, and extended drain capability up to 60,000 miles with oil analysis. AMSOIL diesel oils meet or exceed all major diesel engine manufacturer specifications including Ford, GM, Ram, and heavy-duty applications.

Question 10

How do I become an AMSOIL dealer?

Accepted Answer

Becoming an AMSOIL dealer is straightforward. Visit the AMSOIL website and complete the dealer application. There's a modest one-time registration fee, and you'll receive a dealer kit with product information, marketing materials, and access to wholesale pricing. AMSOIL dealers earn commissions on product sales and can build a business selling premium synthetic lubricants. Many dealers start part-time and grow their business based on customer referrals and repeat orders.

Question 11

Is AMSOIL safe for motorcycles?

Accepted Answer

Yes, AMSOIL manufactures specialized motorcycle oils formulated specifically for motorcycle engines, transmissions, and wet clutches. Unlike automotive oils, AMSOIL motorcycle oils do not contain friction modifiers that can cause clutch slippage. AMSOIL offers products for V-Twin motorcycles, metric bikes, dirt bikes, and racing applications. These oils provide superior protection under the high-RPM, high-temperature conditions common in motorcycle engines.

Question 12

What is oil analysis and do I need it?

Accepted Answer

Oil analysis is a laboratory test that examines used motor oil to assess its condition and detect potential engine problems. AMSOIL offers oil analysis services that can verify your oil's remaining service life, confirm extended drain interval safety, and identify wear metals or contaminants. While not required, oil analysis provides peace of mind when using extended drain intervals and can detect engine issues before they become serious problems. It's particularly valuable for high-mileage vehicles, commercial fleets, and performance applications.
