[Vwdiesel] RE: New oil standards for TDI PD motor, VW 505.01

[Dennis Pantazis]

folks-

this has been beat to death a few times on fred's pages. have a look over
there to get the blow by blows.
www.tdiclub.com dicussions have gone back to last spring/summer.

at the risk of starting yet another oil discussion here are some of the
highlights (i am trying to do this objectionably)

1. 505.01 is required oil to maintain warantee compliance. it's that simple.
there is STRONG language like "you must use oil expressly conforming to
505.01..or your engine WILL suffer serious damage and it will NOT be
covered"

2. sources for 505.01 is the dealer and motul. others hopefully in the
future.

3. 505.01 is also spec'd for phaeton gasser and toureg gasser.

4. castrol 505.01 from dealer is a group 3, not group 4 synthetic. as i
understand it, it is a synthetic made from a blend of dino and synthetic
constituents, not 100% synthetic. it is a synthetic oil.

5. speculation that other oil favorites, (delvac, rotella, mobil) will
propably pass the 505.01 spec, but at this time, they have not had their oil
tested. those companies DO market a 505.01 oil in other countries other than
the us.

6. unverified/unconfirmed/unoffical news from europe is that PD's not using
the 505.01 oil have suffered damage to the pistons and connecting rods.
other areas of concern are the rockers that actuate the injectors.

7. cost- oil cost from dealer is about $7/liter. (i had dealer do my 5000
mile oil change today and it cost $55). before you get worked up on the
higher cost per liter, oil change interval hereafter is 10,000.

as far as another revenue stream on the oil- i don't think so. each dealer
buys their bulk oil from castrol distributor directly. they make more on
vehicle accesories.
