5.0 out of 5 stars Been using this in my diesel truck for years
Reviewed in the United States on January 20, 2021

I have an 06 Dodge Ram 3500 that I've been using this in for years. It takes 3 of these for an oil change. I usually get it at the store but they have been out of it lately. I got it on here for the same price. Most people I've talked to say don't use synthetic for a diesel engine because you'll have leaks. Well I've never had an issue with this and even my owners manual says to use synthetic oil. I usually go about 10k miles between oil changes and don't have to top up in-between them. I highly recommend this oil because it has been great in my truck and keeps it running smooth.

You may think it crazy and absurd ordering motor oil from Amazon but a person's got to do when it's simply convenient. Our local Costco here in the city stopped selling Mobile One and having to drive to any of the local automobile stores is not only inconvenient but you have to put up with snotty kids with attitude. Prices charged on Amazon are decent so you never overpay once you get the final order over $25. What makes this particular oil amazing is the fact I have a 17 year old Toyota which is used only make doctor's appointments and short hops to local places here in the city. As a result I never put more than 3k miles in the course of a year. Oil changes are performed in alternating years.....yes alternating years! Book value is insultingly low however I keep it around just for these purposes. So far it worked for me these 15 years since I retired. Can I have the oil changed by others? Yes but why pay hard earned bucks not knowing what kind of bulk oil is used when I can get the job done in 10 minutes or less knowing it's completed properly .... overtighted drain plug are avoided, oil filter cartridge isn't overtightened with a breaker bar, and all the remaining fluids are validated to be topped off. There's got a be a reason why Mobile clearly states this oil can be used in extended drain intervals!

My friend in high school referred Mobile 1 full synthetic motor oil to me when I bought my 2nd car for brand new. I had always used Mobile 1 from then on for every 5000 miles oil change. Now I am on my 6th car so far, my current vehicle has over 120k miles, and I’m using mobile 1 all the time. I am switching from economy synthetic motor oil 0w20 to high mileage 0w20. Let’s see how the result is after I switched. Amazon has the best price so far. Inflation has increased motor oils in every retailers except Amazon online. Overall I love shopping on Amazon for motor oils.

I like this oil and I usually pair it with either a Mobil1 oil filter or a long life very efficient Fram XG oil filter. We use this oil up to 20,000 miles or one year in some cars that see lots of highway, but in others that have turbocharger and see a good many stop and go miles, we will change oil and filter at 10,000 miles. Later these engines have over 200,000 miles and still do not use or leak oil. Has saved me lots of time and money over the years!

I use synthetic in my pressure washer, walk behind mower, and my Lawn Tractor. This was a good value and I've never had a lubrication issue in any of my small engines. Like many folks, I only change the oil when it gets really dirty. Synthetic is a little more expensive, but the small engines take very little oil.

Came safely, but was delivered a little slow. I use Mobil 1 Extended Performance oil in my Jeep Wrangler Sahara JL and my Kia Soul EX. Provides year long protection at a fair price. Always provides proper levels of protection. Don't see myself changing to a different brand of oil anytime soon.

It pours into my German car and lubricates the engine. The brand has a good reputation. When I tasted it, it tasted awful. I don't recommend a test test. I covered that for you. It's awful.

I bring this and the Mobil 1
Filter to my car dealer and they install for me. I don’t drive a lot of miles each year so this means I only have an oil/filter change once per year. Amazon usually has a good price but it can fluctuate so I recommend you order in advance: amd make your purchase when the price is best.

I only use the top 4 brands now, Mobil 1, Pennzoil Platinum, Castrol Edge and Valvoline. Been very impressed with all of these full synthetic oils after using many different brands in 4 vehicles over the years
I change my oil at 10k mile intervals. OEM oil from the dealer and other "name brand" drained out so black light wouldn't pass thru it. The top oils I mentioned still have transparency at drain after 10k miles
I even use this in my old 2000 truck with 206k miles. I get better mpg when using the top brands like this

Best Oil for VW Golf Mk7 1.4Turbo. My car was burning oil and I've been trying all brands Nulon, Penrith, liquid Moly on 5w -40 and 60w but all cusumed oil within 900klms -1200 klms. I was spending a fortune on oil and black bits coming out out sticking to my bumper. I saw somebody on YouTube trying a this other bran 0w -40w and mentioned if you can't get this try Mobil 0w - 40w and you want see your car burning oil. I have gone passed 1200klms and No oil light. This is still going and checked the oil. It's not bloody burning oil...!! If your car is burning oil than this is the one...!!! My car Golf is running great.love it Mobil 1 0w -40w
