Castrol GTX 5w30 and OEM Oil Filter

 

Since the introduction of the new CJ-4 / SM motor oils, there has been lots of discussion about what to do. For those of you who do not know, the latest motor oil formulations have significantly reduced the anti-wear additive ZDDP (provides phosphorus and zinc). Per SAE papers approximately 1200 ppm of both phosphorus and zinc is needed to prevent premature wear of rotating parts like camshafts in cars that have flat tappets (like older Porsches).

Newer cars have roller tappets to help save fuel. As a side benefit, they do not require the level of ZDDP that non-roller tappets require. Until the advent of the CJ4 / SM grades now currently offered, the ZDDP Levels of quality motor oils provided the phosphorus and zinc we needed.

I am an EX-Royal Purple user -

now use Brad Penn Oil - 1/2 the price of royal purple and 1200 ppm ZDDP levels for my engine.

 

i've been using royal purple in my car for about a year and a half and 22k miles, so 7 changes. I love the stuff. Oh and K&N oil filter.

 

BTW - Brad Penn is Green from the "Old Kendell" refinery in pennsylvania.

 

Motul 5w30 or Royal Purple although the purple burns a little quicker.

 

you have my attention. I dont understand your first post though are you saying its good for YOUR engine and they offer different levels of zddp?

also, is brad penn sold at autozone, discount, or napa?

 

They have changed the formulations for ALL oils recently - even Mobil 1. In an effort to comply to stricter EPA enforcement and to reduce the build up in catalytic converters (which make them less efficient = more pollution).

Well - the downside is that they have less additives that reduce wear.

Less significant if you have the family truckster - much more significant if you have a performance car - especially one with flat as opposed to roller tappet engines.

With the average Porsche Flat Six rebuild costing more than most complete cars, I tend to keep up on what's lubricating my engine as I'm spinning 7000 rpms.

Buy - by the case at:

Kendell Motor, 4901 W Hillsborough Ave - near the airport


BTW - if you are running castrol GTX and you are doing any stoplight or track [hard driving] replace it before you reach 3000 miles - castrol in more than a few tests was one of the fastest oils to break down under load.

 

Advanced Auto Parts. Only the best for my car.

 

Pennzoil, I get it for half price so thats what the car gets.
