While researching the amount of mineral oil to R12 Freon for my 1978 Olds Cutlass, it takes 8 oz of mineral oil to 60 oz of R12. Ratio 13.3%
as you know other 1978-87 G Body vehicles are similar like Chevy MOnte Carlo, El Camino Buick Regals, Pontiac Grand Priz etc etc
I looked at the capacity chart from Four Seasons here:
I compared some other ratios 1878-87 G Body cars from this chart. It was quite a range. Yes I know most say in the chart to look at the hood decal..
For example I noticed a 1987 Buick Regal was 8 oz Mineral oil to 52 oz R12 Freon Ratio 15.3%
1985 Pontiac Grand Prix was 8 oz Mineral Oil to 36 Oz R12 Freon Ratio 22.2%
when I look up that AC parts for 1978-87 G Body vehicles most are the same,
SO not understanding the wide variantion of ratios in different vehicles(they are all G Bodies), I would expect the ratio to all be the same for these.
Any idea of why?
