Having given some input into the antifreeze thread in the tech fixes forum, I thought I'd express an opinion here for your comments:
It seems that all of the specified fluids for use in a 3200GT are a little old in terms of spec. Petronas I fear are making top $ selling us products which were technically superseded years before the 3200GT even went into production.
Which brings us to Selenia Racing 10-60 engine oil, in particular the API SG - CD - CCMC - G5 requirements
What does this long string of alpha numerics mean?
Well the API letter S means the oil is specced for use in a spark ignition engine.
The G indicates the grade of the oil - from around 1985. Since then other grades have been added - 'SN' is the current top grade, which recently replaced 'SM' and 'SL'. 'SH' will be found on most expensive oils, and almost all the new synthetics. It's basically an upgraded 'SG' oil which has been tested more sternly.
The CD was Introduced in 1955 for certain naturally aspirated and turbo engines. Its way obsolete.
The CCMC G5 standard is a pre 1996 standard - Oils are graded G1 to G5. ACEA replaced CCMC in 1996. An A3 or B3 ACEA rating exceeds CCMC G5 in terms of grading.
So in reality any 10-60 grade oil with one of the following ratings from each category will offer every bit the protection of Selenia Racing 10/60.
API - SG, SH,SL,SM, SN
API - SH, SL, SM , SN
ACEA - CD, CE, CF, CG
ACEA - A3, B3
In real terms you can use the follwoing with no detremental effect:
