Went from GC to Mobil 1 T&SUV 5w-30 in my Acura...

[Auto-Union]

Not only is it quite smooth, it revs much more easily. A bit more power. I'll look at the mpg over the next few weeks. I did not have M1 in the car before. No complaints. With GC and winter 89-91RON gas, it was settling at about 30 mpg. I have equal amounts of Mobil 1 (0w-30) and GC stashed, all in all, Mobil 1 is better for me and I would use it preferably.

Likely I will keep using GC in summer to use it up. imo, I think GC offers a hair longer oci, but since I have an existing stash, extending past 3 months 8000 miles is pointless.

thats cool...are you base or type-s?

german castrol is still a favorite amongst many cars!

Good to hear, I want to try Mobil1 5w-40 T&SUV.

My car burns GC just like it did with any other oil... ~1/2 qt at 3K miles.
Also, the engine isn't any quieter or louder compared to other oils I've used.

I'll have a GC UOA coming soon.

Either way, I'm gonna use GC for at least one more OCI.

I am thinking about trying some Mobil 1 5w30 in my car during the winter to see if there is any difference in MPG. I have a huge GC gold/green stash so I will probably use those for the summer time (120F+ thanks to CA desert).

See if all this GC MPG loss is true or not!

Really interested to see if you get any different MPG Auto-Union.

I definately feel the oil being thinner. There is no increase in loudness or "noise". It is zippier. I got an even 30 in the 1/2 tank with the T&S, same as with GC (winter gas) but I was driving it a good bit harder. I was actually surprised to hit 30. I topped back off and will chime in, but I expect to get a lil better mpg, likely I'll get the same 31-32 I got with GC and summer gas.

AU, you're learning....

 

[Auto-Union]

31.5 today. Regular winter gas and all hwy. Needless to say I was VERY surprised. That scenerio would usually yield 29 at best.

I just put M1 T&SUV 5w-30 in my Dodge Neon. The oil was the same price as the regular M1 5w-30. Is there any real difference between the two? I noticed that the T&SUV 5w-30 had different ACEA ratings - but the price is the same?

When it gets really cold try some M1 10W30 and let us know how the uber-thin stuff works?
Or a 50:50 mix of M1 5W30 (or 0W30) with M1 5W20 (or 0W20) should give you a hot viscosity about equal to M1 10W30, but the mix will flow better when cold.

 

[Auto-Union]

32.4, pretty much as high as I've ever seen.

 

[Auto-Union]

fwiw, I'm letting go much of my green GC stash. I think M1 30 weight is better for my car. Willing to trade, see my post in For Sale section.

 

[Lonnie]

AU, is GC a thick 30w and M1 a thin 30w? I'm amazed that the difference can be felt.

 

[Auto-Union]

Yep. Even the tiny step between 30 weight and 20 weight can be felt. Smaller engines are most sensitive, I think.

Auto-Union - I'm putting Mobil 1 5w30 in my 2.2L this Thursday. I'm currently getting 38.4MPG on my 110 mile drive home with GC Gold (34.1MPG to work in morning). On Friday I do another drive so we'll compare the MPG. If anything like your car maybe we'll top 40MPG!
