Works weak in a gas engine.

And where is your evidence to support this claim?
I would really like to see that.

I have the evidence right here.
You see, I learned allot at the school of hard knocks.
One thing is I do not want to be responsible for someone causing damage to something because of my opinion.

I especially learned, do not make recommendations based on my opinion, as my opinion is just that, an opinion.

Where is your evidence proving Shell 5w-40 is a better oil than engineers tell an owner to use in a Porsche, used in all around driving?

This is from the LN Engineering site; IIRC, the article is from a magazine in the UK.

Anyway here is the thread link:

Both Mobil 1 and Shell helix don't come out too well in these tests. Penzoil did pretty well for an inexpensive oil; Castrol Syntex wasn't tested. Red Line was one of the top oils mixed with a few that didn't sound local to NA.

I'll let the experts discuss the merits of the test methodology.

If there's one thing we try and do here at Street Commodores, it's give you, our readers un-biased info on which products are good, and which ones suck. There's so much ________ marketing guff out there, that it can be tough to nut out which products can walk the walk – so that's where we come in, doing our best to sort the Holdens from the Lada Nivas.

A few months back (issue 108), you might remember we did an oil comparison. At the time, we thought it was a bloody good thing, and we don't mind telling you we were pretty proud to publish an article that basically bagged a heap of big name brands. You see, at Street Commodores, we can't, and won't be bought. We like to play things straight. And in the name of playing things straight, we'd like to tell you what has happened since that story went to print.

Basically, we made a few oil companies very cross, and some others quite happy; but we've also been educated some more on engine oils, and being the type of publication that we are, we wanted to fill you in on it. The information we've learned since then suggests the test we performed may be irrelevant. Some sources have advised us that the test we used would have been better served testing some of our favourite greases rather than the engine oils we commonly use on our street cars. Sure, we did the test with the best intentions, with a level playing field for each oil and no preconceptions as to who would perform better than another, but when, and if, we mess up, we like to think that we're man enough to set the record straight.

So keep an eye out in an upcoming issue real soon for an in-depth look at what makes up the contents of your oil, what to look for when choosing one, why certain ingredients are so important and whether the test we used was irrelevant for testing oils.
