Marvel Mystery Oil

Oops. This is for the smaller 3K engine. the 2T clearances were:
..0013"-.0022", only slightly bigger max than the '02 RSX.

 

Informative post TeGGer... As a hobbyist who plays with old
Studebakers, I know that all of the factory tolerances were to four
decimal points. That said, the engines did not have the long lived
characteristics of today's designs probably from the standpoint of
lubricants. Certainly, the materials (used by Studebaker) were up to
snuff to modern variety and included virtually no plastic. OTOH, some
of the seals don't approach the reliability of modern design but a plus
is that many components when rebuilt include modern seals.

One other consideration is that earlier American engines never had to
endure the revs that modern Japanese engines thrive on. RPM's topped
out at about 5K unless the engines were modified.

Oh, I do own a Honda, a 1983 Civic FE project that is getting close to
bearing fruit in the form of gas savings...

Why does Honda now use 5W-20 oil? It's so obscure and it's difficult to
find it in stores. Is it recommended that I switch to Mobil 1 or just
stick with Honda Oil? What are the differences?

 

What's the value? I used to use STP, but that was back in the 70s and
early 80s. I also used 104 octane unleaded for a while. But that's
because I also believed in voodoo and my ability to cut .000 lights.
Well, at least I could do .050 lights and one of my horrible profs
died just before finals.

(I can still do better than .095 on a regular basis, but I don't cut
chickes any more.)
