Oil FYI
My 2005 c230 with 123,500 miles has had Mobil one 0w-40 from new to the last 3 oil changes. Since about 50k I have burned one qt. at about 10k like clockwork. I have sent samples to blackstone for testing and my numbers were comparable to Matt's. My indy shop uses valvoline and swears by it. I have used it the last three changes and have not burned any oil for the full 13k interval. I had it changed yesterday and got a sample for blackstone. Just by apperance the valvoline looks cleaner than the Mobil One did. I will post my oil report as soon as I get it.
Just another tidbit I used to run Mobil one 5w-30 in my 2005 Land Rover LR3 then switched to Valvoline and the blackstone report was much better on the Valvoline. I just changed it with Castrol Edge and will send a report. Castrol Edge just as 5w-30 and 10w-30 weight now, but more will be released this year.


After 39 years with a supermajor oilco I think I know what I'm talking about. And no it's not ExxonMobil.
Regarding your Rover you are probably comparing apples with pears. Valvoline products are not any better or worse than those of other reputable companies. There are many Mobil 1's as there are many Valvoline products. What were you comparing with what? - over how many samples was the comparison made? You really need a good history with both products over many miles to make any meaningful comparison & in identical operating conditions with identical air & oil filtration, fuel etc.

My car burns about 1/2 quart of Mobil 1 0W-40 in 13,000 miles. I'm not giving up the required specifications to save that 1/2 quart.
Moreover, I'd think Glyn's expertise in this area would mean a whole helluva lot more than some anecdotal BS like this. The new-guy-posting-thread-looking-for-cheerleaders thing is getting really old. You posted your info, it was debunked by an expert in the field - stop crying and appreciate that you learned something new.

Some of your first posts here were about how grand your driving skills were, how you have no need for things like ESP and ABS, and how one of our members deserved to be in a crash that could've seriously injured his passenger because he hasn't had professional driver training.
And I've got a holier than thou attitude? Give me a break.
You want to start with personal attacks? Please, be my guest. That'll mean less time we spend wasting our collective breath on you.
Have a nice day.

Can't we all just get along?
My car burns about a 1/4 qts of oil every 6000miles as well. Currently the mileage is at 112,xxx miles. I've been using Mobil 1 0w-30 since day one. I just add extra oil to the car keeping it at 5.8 qts until my next oil change. Not really a big deal to me, since I check the oil level every week or so~
