I have 98 Mitsubishi lancer and recently i swapped my old 1.3 engine for 1.5 engine because my old engine was worn out anyways the mechanic recommend using 20w50 mannol safari which is rated SN while other told me that SN isn't suitable for old engines and the maximum rating i could shoot for is SL " in egypt we have SF, SG, SJ, SL as i know in USA those ratings might be history " is this true that i can't or shouldn't use SN rated oil and what gives oil its rating SJ or SN or whatever
Which rating and why?

SN is completely backwards compatible
So they say, but anti-wear additive levels have been restricted in newer classifications. I've read:
SJ = Just enough.
SN = Not enough.
Please note, I'm not suggesting any particular classification for any particular engine, just making an observation.
SN and SP both supersede SL. SN and SP have better wear protection and better emission system protection (catalytic converters).
What actual facts is this observation based upon?
They must have lots of shelf space there, not only to carry all the grades but all those ratings as well.
The point is, each rating is backwards compatible.
There was no SN in 1998. You are not in the US, look for ACEA ratings. My daughter has a '98 Lancer, I use a 10W-40 with an A3/B4 rating...and it's only SL. Antiwear additives - Lots.
Pretty much, although I did read that here.The humor observation fact.
SP = Practically none?
Is this true even for use in flat-tappet OPE?
For me, with an old tech engine like that, in a hot clime like yours, I would used a mixed-fleet 15W-40 HDEO (suitable for petrol/gas car engines and diesel truck engines).
Something like Delo / Rotella / Rimula / Delvac / etc 15W40, that’s rated API CK / CJ / CI / CI-4 and SN / SL in 15W40. These “truck” oils should be everywhere, are well made, suitable for older car engines and carry a heavy anti-wear package.
