Considerably cheaper than the local parts store for the same oil! Arrived undented and sealed perfectly! Mobil1 has been good to me, and I trust it to keep my engines protected. My wife's driving is downright abusive to her car, A 2nd Gen Prius that gets driven 90 miles a day at 85MPH year round! I'm sure that it's pushing somewhere close to 4000 RPM when she does that, and that's a LOT to ask of that anemic little engine, which she NEVER checks the oil level on! It's been running under this type of abuse with Mobil1 synthetic oils (Usually with the "Extended Performance" 15,000 mile guaranteed on 6,000 mile change intervals) for the last several years and 100,000 miles and several cross-country drives with no problems! Even thought I practically scream at her to check her oil level regularly with the mileage and leadfoot way she drives, she's brought it to me at least 3 times with the low oil warning on, and I am CONVINCED Mobil1 is the reason she still has an engine at all, let alone one with good cams bearings and compression! Well worth the extra few bucks in my opinion!
