shell Rotella T triple protection 15w-40 vs..........

[318willrun]

I was looking at this at Walmart today. 12.87 for a jug. I know many of you use this in the ole' flat tappet cams. I've been using 10w-30 Quaker State Defy (a little more zinc and a dab of synth. blend) with zinc additive Maxx ZDDP. Zero complaints! However, this is about 24 bucks for the QS jug and additive. Just having my thoughts wonder look'n at the Rotella T triple protection Diesel oil..... 12 and change..... and the convenience of not ordering Maxx ZDDP.

I have one Duster on VR-1 10w-30.... but that's a little over 30 bucks...
Not trying to be stingy, just think'n out loud.....

$24 is still cheaper than an unexpected rebuild

I use Rotella in the cuda with a couple squirts of lucas.4 years now with no issues... well not oil related lol
For the Dd I use castrol high mileage.

Just a heads up, Rotella is changing formulations around December to meet CK-4 and FA-4 specifications. I haven't found any mention of the zddp levels yet but I'm still researching.

If it ain't broke why fix it?

Unless it's advertised as having a significant amount of zinc, do some extra research. Most oils, including diesel recommended oils, have had their zinc content reduced. Diesels have been using catalytic converters for many years now and zinc isn't compatible with them....around 2007, I believe.

Not really trying to "fix" it, but if Rotella had the same/or BetteR protection, and it's cheaper?? just nosing....

Stay with VR1

Rotella was all the rage a few years back, before they took the zinc out.

Well, I'm not "too" eager to change anything, I have years and years and never lost a flat tappet cam.

If it ain't broke, don't fix it...

If it ain't broke, don't fix it...

That would depend on valve spring pressures,open and closed,oil change intervals(one of my biggest issues...) ,& cam ramps,on a basic swap...

...i called Shell about 3 years ago and talked to one of their techs,the zinc levels in Rotella were below
1000 ppm even then.

With the copius amount of ZDDP additives on the market does ZDDP levels really matter when choosing an oil now? Shell Rotella T has quite a following with loads of high mileage testimonies.
