I've used Mobil 1 since it came out long ago. I do all my own repairs, have never taken a vehicle to a mechanic except for warranty/recalls. My first new car was in 1968.

protect and invest in your car, less heat build up, less damage at startup with metal protection and lubrication. top of the line product at a really good price.

Use it in all three of my vehicles, 98 F150, 98 Lincoln Mk VIII, 2005 Explorer. Definitely helps keep engine internals clean. Been using this for over 10 years, no complaints

decided to switch my truck to full synthetic because of the amount of time it sits and is usually driven highway miles. already seen an improvement in gas mileage.

I bought this a few months ago and have no idea if this oil is better than any other oil however I keep using it since it is what the user manual recommends.

I’ve been a Mobil 1 fan for years. Started using it on motorcycles. I’ve done oil analysis comparing it to my friends bikes and it was always superior. Since then I’ve been using it on 4 family vehicles with the same great results.

Been using Mobil 1 full synthetic oil for years in all three of my cars. I have full confidence in the product consistency and quality. Now converting my son to do the same with his cars.

I am using 5w30 for a G37 and 0w20 for a Prius Both engines run extremely smooth Very noticeable difference between this oil and the previous dealership oil

I am a DIY oil change person and have been using Mobil 1 in all my and siblings vehicles for quite sometime. And Kubota diesel tractor (bought new in 1989). Free shipping from Sams is a bonus.

Have used mobile 1 full synthetic engine oil on my car for many years and been very satisfied. The car now has got over 240k miles and still runs smooth.
