LubeUdo FAQs

Q: How can I take advantage of Flat Rate Shipping?

A: When checking out, you'll see a USPS Medium Flat Rate Box and a Large Flat Rate Box option.  We can fit up to 6 quart bottles or 7 eco-pouches of oil in a Medium box.  Or, 8 bottles or 10 eco-pouches in a Large box.  These can be very affordable options for shipping heavy oil as they go to any US location for one flat rate - including PO Boxes, APO, Alaska, Hawaii, Puerto Rico, Guam, etc.  If you are ordering more than will fit in one of these boxes, please select either UPS Ground, USPS Parcel or Priority mail.

Q: What API (American Petroleum Institute) Service level is right for my car?

A: For gasoline engines, the latest engine oil service category (API SN) includes the performance properties of each earlier category.  If your owner's manual calls for an API SM, SJ or SL oil, an API SN oil will provide full protection.  Similarly, if your car requires one of the manufacturers standard oils, like Ford WSS-M2C930-A, an oil labeled as WSS-M2C945-A or 946-A are higher performance oils and will more than satisfy the requirements of the 930-A oil.

Q: Can synthetic oil be used in new engines?

A: Yes.  Synthetic oil is perfectly safe for use in new engines and is actually required by many new car manufacturers.

Q: Should new cars be broken in using conventional petroleum oil?

A: No.  Synthetic oils are safe for break-in and offer immediate advantages to new engines.  The only engines/platform for which synthetic oils are not recommended are Mazda rotary engines.

Q: Can I mix synthetic oils with conventional oils?

A: Yes.  Mixing synthetic and conventional oils will not cause any problems.  The oils are compatible with each other.

Q: Are synthetic oils worth the extra cost?

A: Synthetic oils are superior to conventional oils because they help maximize horsepower, improve gas mileage and provide a smoother, cooler operation for the engine, prolonging engine life.  The benefits of synthetics easily outweigh the extra cost.  The Mobil Advanced Fuel Economy oils estimate a 2% increase in fuel efficiency saving $400 over the life of the car.

Q: Do I need to use a different type of oil filter with synthetic oil?

A: No.  You can use any type of oil filter with synthetic engine oil. 

Q: Can you go longer between oil changes if you use asynthetic blend or full synthetic motor oil?

A: To maintain your car's warranty, you should follow the manufacturer recommended service intervals.  You'll find that cars that ship with (and usually require) full synthetic oils will have much longer service intervals than cars that ship with conventional oils.  A larger sump and therefore, higher volume of oil is part of the equation.  If your car is no longer under warranty, many feel comfortable extending their oil change interval by 50% or more when using full synthetic oils. It's a good idea to install a higher quality oil filter if you plan to extend your drain intervals with Synthetics.  Mobil 1 Extended Performance oil offers 15,000 miles of guaranteed protection.

Q: How does my car's "oil life monitor" work?

A: Many modern cars use computer software algorithms that determine when to change oil based on engine operating conditions. The monitor looks at mileage, speed and idling time to calculate when you should change the oil. Other systems employ conducting plates that measure the capacitance of the oil.
