Change oil every 20,000 miles on my last 7 Toyotas and Scions,Every 5000 miles i change the mobil 1 fliter. with new one.Always use Mobil 1 oil and Fliters

Have used this product in my last 5 corvettes and can say that in my opinion it is a very good product and does exactly as advertised. I have never entertained the thought of another brand as this product has excelled in my opinion.

Have had excellent results using this product. It has given me confidence in engine protection and good results in fuel economy and no significant oil usage between oil changes.

I've always used this from the time my car/truck is new, until I sell it. If it's good enough for the big boys, it's good enough for me and all my vehicles.

It’s ok. I’ll be switching to amazon basics oil for my changes. Lower price and meets all the same specs, even beats it in the cold flow test and it’s cheaper

[This review was collected as part of a promotion.] Just what we needed for some of our lawn and mechanical equipment to keep everything running smoothly!

I have been running Mobile 1 in all my hotrods since the late 70's! This oil keeps everything like new internally!! I even use Mobile 1 in my Harley Davidson! (V-Twin).

When it gets -20 degrees actual air temp here the other synthetic motor oils I've used would allow the engine to squeal a bit on start-up. Not so with Mobil 1 5w-30. I really like that. I have a Chevy Silverado 4.8L.
