It's usually either comparably or better priced than the M1 turbodiesel 5W-40. I'll run it and if I happen to buy it twice in a row I'll see if on the second run the consumption decreases any. I'm nowhere near worrying about use rates but I'm curious etc.
How much is an oil analysis.
I'm pretty broke and since the car runs fine I am having that "if it ain't broke don't fix it mentality".

I have read numerous reports about switching a high mileage car from traditional oil to sythetic oil.
Yes.... synthetic is better, and provides better protection..... period.
However, the naturally occuring "buildup" that happens with traditional oil..... will all be flushed out when you switch to synthetic..... which "MAY" cause seals to leak.
Not always... but it may.
But... because this is a turbo engine.... I would be inclined to use a synthetic blend in your particular case..... and hope for the best. I bought the SVX with 145K on the clock..... and use good quality traditional oil.
The Brat has God knows how many miles... and runs like $hit anyway.... I'm all about the Wal-Mart special oil - LOL
The WRX and the Tribeca were new when I bought them.... so synthetic... always... every time.
I've used Mobil1 since the WRX was new..... I just turned over 50k miles, and have since switched to Royal Purple for added protection. I actually did it to "splurge" a little before a recent race.... and now I'm hooked.... Royal Purple is awesome stuff.
20-minute balls-out timed lap battle sessions at 130mph+, 6K+ rpms.... ANY oil is going to burn a little... or so I thought.
Royal purple barely looked used after three 20-minute sessions.... and didn't smell at all...

I don't think I'd switch at this point. I think someone mentioned earlier that the viscosity of synthetic allows it to seep through the seals better on high mileage vehicles. I had a ford truck a while back with 150,000 on it and the seals were leaking so instead of replacing the seals I switched to a synthetic blend and then a conventional. Leaking went away. If you haven't used synthetic, I'm not sure I would switch now. It might hurt more than help. Just my opinion.
We've tried almost all of the expensive boutique oils in our $30,000 circle track modified engines. Redline burnt, Royal Purple turned into Royal Sludge after one race etc etc. Out of all of the boutique oils, the only one that didn't burn and actually showed some hp on the dyno was Joe Gibbs XP1. We used to run M1, and were very happy with it, but have seen even less wear with the Joe Gibbs and a little more HP. The only set back is the cost. It's a bit pricey at $180 for 12 quarts.
