Michael,

 

I use 20w-50 in all of my classic car engines.  Now, if I drove them in the
winter time I would probably consider the 10w-40 option as it would have the
lower 10W viscosity for those cold morning start ups.  So you are fine.

IMHO Michael that will be absolutely no problem.

On Sun., Mar. 20, 2022, 4:45 p.m. Michael Oritt via Healeys,

Through a stupid mistake on my part today I purchased eight quarts of 20w50
synthetic Amsoil rather than the 10w40 I normally use year-round.
Unfortunately I discovered this mistake this afternoon only after I
completed the oil/filter change.

 

I am concerned that this higher-viscosity oil might in some way damage my
engine.  It has been about 60-70K miles from the engine's having been
professionally rebuilt and while oil pressure has fallen somewhat over the
last several years the gauge still indicates about 40 psi at 2500-3K rpm's
and about 20 psi at fast idle with 10w40, in both cases with hot oil and at
normal engine operating temperature.  I took the car for a very short spin
after completing the change and I am quite sure I did not did not get the
oil up to full operating temperatures but in any case the OP did seem a few
psi higher than what I am used to seeing

 

At this point I have about $125.00 invested in the mistake:  seven quarts
and a new K&N filter.  If my fear is verified by your opinions I am
certainly willing to drain and refill--I certainly do not want to be driving
around if there is a real risk of causing damage. 

 

I eagerly await the group wisdom.

 

Best--Michael Oritt
