I use 5w30 extended oil in all my vehicles. I usually charge the oil about 7000 miles, one time went 9000, the oiil was dark but still looked good.

I’ve always used Mobil 1 but this oil holds up longer and I burn less of it between oil changes. We have 4 Volvo’s and this oil goes in all of them

I've been changing my oil every 15k miles and have not seen severe loss of oil nor burning smell this product lasts!

I use Mobil 1 not only in my car but in my lawn mower, garden tiller, edger and generator. Superb protection at a great price.

Slightly more expensive, but Mobil 1™ Extended Performance 5W-30 lasts longer with better base oil and great additives.

We like the performance of Mobil 1 and it is the only oil we use in our vehicles.

I have been using Mobil 1 for couple decades and it is still the most trusted product for my car.

For me, mobile one works great, the oil stays cleaner and last longer in both of my cars !

I want the best possible oil I can buy for my engines and have used Mobil 1 for many years.
