Trying a new oil.... QS DEFY

[Garak]

It could be a mistake with a variety of possibilities behind that (typos, cut and paste errors, being clueless) or it could, I suppose, be intentional. Notice how we've never seen an MSDS that listed primarily Group I on a synthetic oil, but we've seen the reverse. There are mistakes all over the SOPUS product data sheets, too. Pull up Formula Shell 5w30 and Formula Shell Synthetic 5w30 (at least the Canadian sheets). Going by those sheets, they are absolutely identical products, without a single number or letter changed, other than the inclusion of the word "synthetic" in the product name.

As for MSDS in general, I've seen more than I'd ever care to admit.

Same here....

Truth is we will never know. So we can all believe what we want!

You're absolutely right. Anything is possible, but we do have to take these sheets with a grain of salt at times. Neither a PDS or an MSDS is a recipe. I might have more faith in an MSDS if enforcement was very specific on them, or if we knew that these companies were very picky about having correct data on their other sheets. Castrol puts minimums down, SOPUS can't keep their product line straight, and Mobil likes to hang onto sheets long after the product is dead and buried.

The funny thing is that these companies' sheets could all be perfect and be made perfect for free if they gave the data to any one of us select group of OCD nuts to straighten out! But, we take lubes more seriously than some of their tech people, obviously.

So back on topic. Has anyone had any experience with Defy slowing a leak? The 0w20 is smooth as butter in my Taurus but hoping the 5w30 Defy will help slow down the leaking. The extra zinc will make up for the viscosity jump

I shifted to it during the last year or so I owned the Buick Park Avenue with the 3800 NA engine. The car had been burning or leaking some oil (though I never spotted a leak, or oil on the ground) since I'd owned it. QS Defy did slow the consumption to about a quart in 5000 miles -- which for me was 6 months' driving.

Off topic but along those lines: My trust in Valvoline, of which I was a huge fan, is now wavering after their response concerning the Nextgen 5w20 noack failure and recent ATF issue. Trust plays a huge part in all our choices.

I wouldn't worry too much. MaxLife did exactly what I expected of it in my old F-150 where non-HM oils failed, so it did exactly what I wanted. Then again, oil pressure falling below minimum is a bigger risk than a high NOACK.

I've used DEFY on my 4th high mileage(HM) OCI.
My first 3 HM OCI's(all OCI are 5W30 BTW) were with MaxLife which, after the 3rd OCI, did start to slow(but, not completely stop the leaks) the oil dripping on my '80 Firebird FORMULA V8.

My 4th OCI was with DEFY and I couldn't believe how much quieter/smoother this oil made my engine, even moreso than ML. Maybe a little tooooo quiet/smooth for this particular V8 as it lost some soul.

I really like the DEFY but, recently just happened to catch another sale on ML for my 5th HM OCI coming up in the Spring/Summer of 2014.

After this 5th OCI w/ML, I may switch to DEFY for good(IDK) in the Old Bird

True, mine was a knee-jerk reaction...
