I use Mobil 1 in our Ranger , Mountianeer and porsche. I always felt more comfortable using it , any opinions?.

 

Just do a search on synthetic. And may the Lord have mercy on your Soul.

if youve had luck using it i would go ahead but i always use what the manufacters recommend. motorcraft in our trucks, castro in the bmw she gets the dino version too and the mercedes both get mobil1

 

i only use motorcraft or conoco 5w20

 

I use the Mobil 1 4T formulation...because Triumph tells me to. I use Motorcraft in the F150 because that's what Ford recommends.

I believe the Motul synthetic is pretty equivalent.

Motorcycle Consumer News did an in-depth comparison of the high-end MC oils a few years ago, I believe with the cooperation of a Gold Wing club. I don't think it's on the internet. And I think Mobil 1 was pretty highly rated.

I ran the Mobil 1 in 0W-20 last winter because our weather gets so cold here. Then this spring I checked the Mobil website and the 0W-20 diesignation has been replaced by 5W-20. I suspect it is the same oil, just that for marketing purposes it is way easier to convince people to use something that includes the numbers they see in the owner's manual.

I notice that Canadian Tire is marketing a 5W-20 in their own brand synthetic here in Canada. This is likely made by Esso (Exxon).

Because my truck in operated in very dusty conditions I follow the severe service recommendations for oil change intervals. This does kind of negate the long life advantage of synthetic. The main reason I use it is for those -40 cold starts.

At least when you pay the price for a full synthetic you know what you are getting. Partial synthetics don't seem to have any particualar standards and don't generally indicate the percentage of synthetic content. They may actually be a much poorer deal.

I have been running synthetic oil made by Mobil, Esso, Penn, Canadian Tire and Texaco in both gas and diesel engines for years. I have never had any sort of problem and I always feel my engine is better protected with synthetic in the crankcase.

When I lived further north in Saskatchewan and was driving an F250 with a 6.9 litre diesel I decided to treat the old beast to some good 5W-40 synthetic. That engine took 10 or 11 litres of oil for a change and I went with Mobil Delvac. The WalMart where I had it done said I set the record at that time for an oil change at $150. The upside from the usual 15W-40 was that when I started it at -40 the oil pressure guage didn't take a couple of minutes before it moved!

 

in my humble opion mobil 1 is the only way to go when it comes to synthetic oil. that is all that I will use.

Nice test on Mobil 1 vs Amsoil ASL. They ran these oils to 18k and 14k miles respectively and tested the oils without changing them.
