Now StevieC, every time a new oil spec comes out folks start talking about doom and gloom. Been doing it since 1955. Modern technology will see you through.
I don't want "modern" technology to see me through... I want them to leave the formulation alone. I don't see why they have to modify it when all oils today offer a great level of protection and don't sludge like way back when, when used under normal use.
Why make the oil contain less?
That's all I'm saying... I'm not trying to doom/gloom a new spec just because... I'm being truthful.
If one reads what the proposed changes are, there are some pluses, but longevity of the oil and the additives which, IMO, protect the engine the best are being reduced too far for no good reason.
At some point catalytic converters have to be cheaper to replace than more frequent oil changes because of a reduction in ZDDP etc.
If you ask me it's a ploy to get older cars off the road and make people buy cars more often because the level of protection isn't there like it used to be. All in the name of "catalytic" protection and "increased fuel economy".
Funny how with all the modern technology fuel efficiency remained pretty much the same, yet the complexity of working on a vehicle went up dramatically. Can you say "Dealer profitability"
And now we all of a sudden (and recently) have to use and oil that contains less wear additives like ZDDP because it might be harmful to the emission system? Why???
Why not super-protect the engine with a robust oil and it won't damage the catalytic because it won't consume oil in the first place? Oh wait... That's right... Because they want to sell more vehicles and because they feed us the line that "Modern engines don't require such high levels of ZDDP etc." Only engines like those that have Flat Tappets do. Last time I checked there is still a lot of "Metal on Metal" contact in an engine. Sure there is less today, but not enough to warrant the drastic reduction of additives that they have done this far and intend to reduce further.
*UGH* Maybe I don't get it...
Not trying to give you a hard time... But it bothers me that the industry keeps reducing additives in oil. It will probably make for a captive market for Amsoil, RP, RL etc. who either believe in formulating their own way without API approval, or rely on some older approved specs like SL.
