[Healeys] oil weight

[Patrick & Caroline Quinn]

G'day

 

It's a good thing that I don't take a similar approach to subjects and
comments that come up on this list. For if I did I would be spending all day
responding to the idiotic, ill-informed and close to slanderous comments
that some people foolishly make.

 

Luckily I have more relevant things to do with my life so perhaps it's time
to move on.

 

See ya!

OK, I'll bite.  How, exactly, do you formulate an oil for an older engine
(besides adding lots of ZDDP for flat tappet cams)?  Except for (possibly)
looser clearances--not necessarily so if you have a good machinist--what is
the difference between an older iron block and a newer one (I know many
modern engines are Al), Al pistons, steel con rods, babbitt bearings, etc.  

We are running modern oils in:

- a 1946 Chevy 2-ton truck
- a 1955 T-Bird
- a 1956 BN2/100M
- a 1965 Mustang (289)
- a 1967 BJ8 (that gets 4-5K miles/year and uses--drips, mostly--a quart of
oil every 3,500 miles)

... with no issues with the oil whatsoever.  Sorry, but while I'm sure
Pennrite is a good oil, unless you/they can tell me exactly what needs to be
formulated for older engines it sounds like marketing blather to me.  If
'formulated for older engines' means you get lots of sludge and gunk in the
pan thanks, but I'll pass.  I had the timing cover off my BJ8 to replace the
seal the other day and was astounded at how clean it was; not a speck of
crud (110,000 miles since the last rebuild).

Note there are strict requirements (per SAE) for oil viscosities, so 20W-50
Pennrite is the same viscosity as 20W-50 KMart oil and, BTW, there's no good
reason not to use a multi-vis oil; you're doing your top end a disservice
every time you start the engine if you don't.  I believe Pennrite makes a
XXW-60 oil, which should give a little more oil pressure if your engine is
oil pressure-challenged.

Any racers on the List care to chime in?  Richard M., aka 'Boy Racer,' are
you on here?

Gearboxes?  No question, modern synthetics--like Redline MT-90--are hands
down the best (if you can live with the leaking--I can).

ps.  I'm not trying to be antagonistic Patrick, I just don't buy the
Pennrite line

I don't think you read was I said.

 

Not a problem using modern oils, but they should be oils formulated for
older engines.

 

Take for instance the oil for the gearbox. I certainly wouldn't use an oil
that contains a detergent.
