Blah. I've fed my Jeep the cheapest whatever is on sale dino oil for the past 10 years and 150K miles and the engine still runs like it was new. The most important thing is to change frequently and use a good filter. Changing the oil every 3-5K, it basically doesn't matter what oil you use. If you feel better about it, so be it, but the difference between oils PALES in comparison to changing it frequently.

Oh yeah, read bobistheoilguy.com for a great resource for oil. Might even learn something about the coconut/baby derived Motul oil.

 

you can save 2 bucks a quart on motul full synthetic by getting it from a kawasaki motorcycle dealership under a kawasaki label. same stuff, even says packaged by motul in small print on the bottle.

 

You can get Amsoil direct from them online... According to the Motor Oil Bible (M.O.B) Amsoil scores higher than any other 5w30.

 

I don't know about 3 to 4 mpg better. But Motul is good oil.

I have an ARC catch tank and oddly enough the motul smells better when you get a wiff of it coming from the catch tank. It still stinks... but a little less nasty....

 

I wish I can get them to foot the bill.

 

as you can see from searching drivers have different opinions in oils, but MOBIL1 is the most popular i believe, i'd def would go with the most trusted (mobil1)

 

I remember when M1 came out back in the late 70's or early 80's, it was as thin and colorless as water. A friend got some for his pick up, 5W30 I think, and that stuff was just like water. Now it's just as thick as any dino oil.

 

never heard 3-4-mpg from oil alone ... i use amsoil since 87 in everything.....

 

I still think Mobil 1 is thin as hell. If you pour it into your car and pay attention to the last few drops as they fall out of the jug, it pours very thinly. Most conventional 5W30 oils that I've seen are a lot thicker than that and have more of a gooey type look and darker color as they pour.

 

Motul is great...went to autoscope in Plano today and had motul oil and diff fluid put in today for dirt cheap...great shop, mostly a german auto tuner shop but they will work on our cars

 

Mobil 1 in the USA is now a group III base oil. Nothing wrong with that at all. In fact, it pretty much equals the "True" synthetic PAO's in performance except in very cold condition (-40 degrees) pour point. The main gripe people have is that Mobil is now using a less expensive Group III base stock, but charging the same for the product. Group III based oils can legally be called Synthetic as they are very highly processed and converted from crude sources.

The new Mobil 1 is still an excellent oil and will protect very well, but some don't like that Mobil didn't cut the price and pocketed the extra profits. Amazing. I thought companies were supposed to be as profitable as possible for their shareholders. This is America, not state run after all.

 

Since you do own a BMW, you should know that the capacity is close to 7 qts right? That's one of the reasons why it can have a longer OCI.

 

That is incorrect. Mobil is just as "thick" as any other oil in it's viscosity class. (with a range that is). The reason why it pours better when cold is because synthetics feature a MUCH better cold flow capability. Not because it's thinner/thicker. You WANT this of an oil.

 

+1 on jeffs' post. what the oils thickness at cold is not going to be what it is hot. synthetic does not change viscocity as much with temp as dino oil.

 

heres some good info...
