high mileage oil

[02rubya4]

Anyone here use it? I picked up 5 quarts of Mobil 1 5w 30 high mileage. My car has 106k and was wondering if there are any one uses it or if there are drawbacks.

Tia fellas

You'll be fine along with everyone else that buys into the Mobil 1 marketing.

next time if you want a better quality synthetic at the chain parts store pick up the GC 0w-30 & mahle filter.

Gc? Never heard of that. Plus I've been using regular Mobil 1 for some time now my only issue was that if additives in the high mileage will f anything up also brings up another point is it an issue to switch from 5w to 0w or is it ok to just do

Why does everyone knock mobil1? You dont become the leading, probably most widely available, and reasonably priced FULL synthetic oil (as in, base stock and all) by selling garbage. I can attest that in my last car, an '06 mazda3 2.0. I ran that oil since I got the car (brand new). After 5 years and 100k miles of beating the shit out that engine, constant high revs, running it to the rev limiter daily...etc, all trying to get to class/work on time, that engine was SPOTLESS. I religiously changed the oil (5w20)/ mobil1 filter every 5k. Even during the summer months I would lose at most 4 oz between OC intervals. Something else that helps, I always let the car run atleast a minute or until the revs came down to low idle on a cold start b4 driving when its warm out, or in the winter, atleast 15 minutes, for the cars sake and my own. ( -14*F here last winter) So for me, say what you will, knock it all you want, mobil1 it is. It proved me once. ::now thats thinkin with your dipstick::

GC is no longer green :-). I still have bunch of it for my other car. Right now I use Total 0w-30 and Mahle filter and change it every 8-9k. Blackstone reports are perfect.

if you read my OP i'm not looking to start an oil debate thread because i know there is thousands of them on AZ. Im just curious about if the additves are bad in the long run for our engines (1.8t)

Anything that goes inside an engine is hard to review scientifically without some serious and very expensive testing. I mean long term tests with oil analysis done over intervals, plus a full tear down of the engine to measure wear and deposits. and that won't still be definitive, as you need to have several cars driven and maintained identically, each with a different oil used.

One thing is for sure, do not use regular oil in 1.8T engines, as the sludge problems that caused are well documented.

It actually isn't a 'true' synthetic. You need to check you information and stop buying into the XOM marketting.

This has been beat to death on bobistheoilguy.com which is a great source for related information.

After I read a bunch of data sheets I picked Total Energy9000 5w40 due to specs, cost and availability. Been happy with the results, run 7500km OCI and never had an issue with cold starts. And by cold I mean -40* cold without being plugged in.

He's right.
