Greg and All
Penrite Oil's recommendation for our Healeys is HPR 30 a 20W/60
viscosity. The older cars do really prefer a thicker oil, when these cars
were manufactured there was no such thing as multi-viscosity or synthetic
oils.
I run it in my 54 BN1 and with an non-rebuilt engine that leaked badly with
Castrol 20W/50 but with the HPR 30 has cut down on oil usage and very
little to no leaking. Also in the gear box I have Penrite Gear Oil 30 a
non detergent 20W/60, which also leaked but not anymore. In the
differential is Mild EP, recommended for the early 4 stud axle when the 5
stud was introduced in the BN2 the recommended flavor is Hypoid 80W/90.
If any one would like a brochure packet please furnish your mailing address
and I'll get one in the mail. Should you have other cars besides Austin
Healeys let me know and I will include a Penrite Lubrication Recommendation
sheet for each.
If I can be of service just let me know.
Merry Christmas and Happy New Year
