## Questions & Answers

**Q: what is the oil change interval for mobil 1 advanced full synthetic?every 5000miles or 10000miles?**
A: The official ExxonMobil warranty interval for Mobil 1 FS 0W-40 (aka European Car Formula) is 10,000 miles or your OEM recommended interval, whichever is greater. This comes with the further stipulation of an oil change every 12 months if you don't reach a mileage cap, first. If your vehicle is still under manufacturer's warranty, you'll want to follow those OEM service intervals, though.

**Q: I have 80k miles on my nissan murano 2010 and i don't have oil leaking problem. should i still use this oil? or  'mobil1 extended performance' version**
A: It's really up to you. I'm not completely sure if it's a seal conditioner additive that differentiates the extended performance from the regular mobil 1 but things tend to wear with age. I  put it in my 2008 V8 Pathfinder which didn't have an oil leak issue and it works well. I converted over when it had about 90K on it. I also have a 19 year old car that was leaking oil and was significantly reduced when I used the Extended Mobil 1.

**Q: Would this be safe to use on a Lawn Mower that came with an "SAE 30 Small Engine Motor Oil"?**
A: As other astute people here say, generally use SAE 30 or 40 straight weight.  Most small engines use solid lifters and need high viscosity to protect motor.  Most small engines are SPLASH oiled.  Meaning no oil pump.  Although other oil seems to work, it may be prematurely wearing your cam shaft lobes.  I also recommend periodically adding ZDDP or zinc additive to protect cam and engine. Now of course if your owners manuals says use 10w-40 do that.  It may be a modern oil pump motor.

**Q: Is this ok for 2013 Mazda 3 Skyactive 2?**
A: Been running Mobil 1 Full Synthetic Fuel Economy in a 2014 Mazda 6 that's at 55,000 miles now, no known issues, changing it every 7500 miles as specified in the owners manual.  In checking around at some Mazda forums back when the car was new, other than the bottles of factory Mazda oil available at the dealer counter, this oil seemed to be one of the consensus picks for SkyActiv engines.  The factory Mazda oil has a molybdenum additive and is much more expensive than this Mobil 1.  Some suggested getting a molybdenum additive to go with the Mobil 1, however I've never done this.  (Note, if you go to a Mazda dealer for a synthetic oil change, it will almost certainly come from a giant tank of Castrol synthetic or whatever.   Ask 'em.  To get the pricey factory Mazda oil, you need to go to the dealer parts department).
