      Very nice. Put this is a freshly rebuilt engine after taking out the break in oil. Had a 2 Miles per gallon increase. Very impressed. Also feels like a slight increase in horsepower.

        The only oil I have used since I started doing my own maintenance 8 years ago. When your car is a necessity for getting to and from everywhere maintain it with the best. The extended interval is great too. It's garunteed for 15,000 miles but i usually change it every 10,000.

          In the us oil manufacturers can say a oil is full synthedic even when it's not just like Mobil one they used to be but they lost one of there contracts with Castrol but it is synthedic they start off with crude base stocks and then make it synthedic unlike royal purple am soil and red line that are made in a lab and start off as synthetics there is not Mitch difference except the real full synthedic oils don't break down as quickly as the fake full synthedic oils cough cough Mobil 1 but I'm done upswing Mobil 1 a dolor more you can get real full synthedic oil like royal purple

                    I bought a 97 Honda accord with 113,000 miles and the top end had been rebuilt. I decided to try synthetic. This product works great. Increased gas mileage by 3%.

                        Advance should allow the store to price match to the on line prices, especially if you provide the free shipping for the purchase value exceeding x.xx dollars. In my case Advance could not ship the product (EPA, DOT, etc. regs.) but i could pick up at the store with the order already picked. It seems that taking up the employee's time to pick my order costs Advanced more that allowing the store to match the on-line prices. I got the filters in the store at the same price but had to return home , place an on-line order and then return to the store in order to get the on-line price savings ( which were a very good savings).

                        • Q:

                          My car recommends 5W-20 oil. Can I substitute this 5W-30 product and expect the same or better performance or is it just not recommended? I only ask this because it seems you are not offering the 5W-20 Mobil 1 EP product.

                        • Q:

                          I have a 2000 Toyota Celica GT with around 110,000 miles on it. The engine burns oil probably about a quart every month, due to bad piston rings (a known issue with these engines) but the engine runs great and strong. Do you think the MOBILE 1 EP synthetic oil would improve this situation? Would you recommend another MOBIL product for this problem?

                            I have experienced this many times as a 33 year Master auto tech. Synthetic oil is more viscosity so it may use more oil with synthetic. Just use cheap 15w40 conventional oil, if it still uses oil go to a 20w50. And if it still uses oil, it's time to get a new engine. Synthetic oils are best used on healthy engines. If an engine is leaking or burning oil, the condition will get worse with synthetic at no fault of the oil.

                          I have a 2003 Forrester 2.5XS (71K miles). In my latest service from Subaru they said I have a head-gasket leak. Nothing major, but to keep an eye on oil level. I've been using Mobil 1 for the past 2 years. Is there anything I can add that will help seal this leak? Thanks, P Malloy.

                            Bars Leak Head Gasket Fix - part# 1111 should work fine for your application as it combines antifreeze-compatible sodium silicate sealing liquid and various-size gasket-sealing particles to stop head gasket coolant leaks without draining the cooling system.
