Review: スバルインプレッサには丁度良い量のオイル ４リッターでは足りない５リッターでは僅かだが余る
Review: 年間の走行距離が多く（約４万ｋ）交換サイクルの長いオイルを探してました。こちらのモービル１は国内生産の金属缶入りではなく海外生産のプラボトル。同じモービル１でも違いがあるだろうと考え購入しました。 エンジン始動後の回転の伸びの良さや静粛性も満足のいくものでした。5000ｋ毎の交換プラスエレメント代を考慮すると３回分に余りあるものと思います。コストで計算するとお得では。 あとは耐久性。そちらはこれからの検証です。

## 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).

*by ソ***ピ on October 11, 2025*

今まで４リットル缶だとエレメント交換までするのに足りなくて別途１リットル缶を購入していましたが少し余っていました。この商品に辿り着きとても満足しています。このオイルは初めての購入なので使用感はモービルさんなので安心してこれから確かめていきたいです。
