Concerning engine lube on the L134. I live in the Philippines where we are running around in temperatures of 30-38 degrees most of the time .My problem is i cannot source any SAE 30 MONOGRADE oil here . Plenty of SAE 40 around . Would it be ok to use the SAE-40 or is it going to trash the engine ?
40 will work for 30-38 degrees F. Or you could use 10W30 _________________ Wes K

Since he is in the Philippines, that would be 30-38°C, not F, so 86-100°F. SAE 40 should be fine. Castrol lists SAE 40 for temperature conditions above 60°F.

My parts supplier, Desmet in Belgium, says to firstly only use mineral oil. No synthetic or half synthetic. Also , he advises to use SAE30 or if you cantfind that, Castrol has a 20W40. So I guess you are ok with the SAE40, as long as it is mineral oil.

Shell Rimula or Rotella 15W40 is ideal for jeep engines & good in the stated hotter climate.
There is no valid reason to use a single grade or straight mineral oil & doing so reduces the engines service life over better more modern oils.
The reason "some" folk are getting paranoid is that "some" additives are being deleted from "some" oils so as to meet strict environmental issues. Newer engines are designed around these new requirements.
This Shell oil is one that has not dropped zinc/phosphorous content etc. essential ingredients for our older engines needs.
So "there is no reason to throw the baby out with the bathwater." _________________ John GIBBINS

This is the new young blood thinking and I really don't agree with it.
Engine oils today are designed for use in today's engines period. Today's engine have tighter running clearances then ours, run significantly higher temps in excess of 200F then ours and as already mentioned have dropped many additives by law. There are dozens of discussions on this topic over all the web sites and technical papers floating around most web site. Mineral is still the main recommendation for break-in on antique engines. Straight vs multi-weight is not an important issue. The important issue is that the oil used be of a composition that is compatible with your engine. Shell among other oil manufacturers offers oils designed for our engines so why not use them and leave the experimentation with the modern engine fluids for the folks with deep pockets and a lot of time on their hands. _________________ Wes K

I use & recommend Shell Rotella [or Rimula] in Jeeps. _________________ John GIBBINS
