UMM, Using a cheap dino oil and Moly or other anti friction additives is silly in my opinion, as you would be better off spending your money on a better oil that has all the required additives included in the first place.
Changing to a fully approved synthetic oil (Including the cheaper HC synthetics) of the best possible viscosity range and with all the required approvals and ratings will probably produce a better result.
With some engine types and turbo diesels in particular, using poor quality dino oil results in black death (Sludge and varnish), due to oil breakdown and lack of detergents.
The combination of bad oil and good additives, reminds me of folks in the US who use cheap oil filters and then say it's OK because they change their oil every 3000 miles. That doesn't work either!

I would like some feedback on the Schaeffer #132 Moly EP additive.
My family drives beater cars and I want to squeeze as much life out of them as possible. They all use a little oil (about a quart about every 2000 miles), so using a premium oil like Schaeffers or Amsoil with extended OCI would be expensive with the quart of make-up oil every 2000 miles.
I am thinking of using the Schaeffer #132 Moly EP additive with an inexpensive dino oil like Formula Shell or Chevron Supreme.
A search of BITOG shows some old posts about using the #132 additive as part of the famous "MolaBrew", but nothing recent. Are any of you using this stuff? If so, what are the results?
Also, will the Schaeffer 132 have any compatibility problem with AutoRx? Thanks for your help.
