Hey Tex, i cant see how there could be any link with oil cracking cylinder heads. engine development has come to a level only dreamed of before, take for instance say a Subaru wrx, lots of power output from a 2 litre engine, compared to say any old 2000 c.c. engine. yes, the detergent oil of today is designed for a purpose, look at compression ratios, engine r.p.m.,s. todays vehicles cruise effortlessly at~1500-1700 revs@ say 100 klms or your 60 m.p.h. how many revs did the older vehicles do at that speed, would you say double or close.? today you start with a new engine, fuel injected, thus metering a perfect fuel ratio for clean running, oxygen sensors, temp sensors to regulate fuel richness at a given temp, no flooding, accelerator pump to give a couple of pumps to assist starting, no screaming revs(unless you are a hoon or leadfoot). add up the amount of revs an older car did compared to todays car, it has to be double for a fact. your oil has to stay cleaner with these facts in mind, also unleaded is a cleaner fuel. as for the old wives tale you can put detergent in your old engine, i WONT, and i repeat, i repeat, i never will because i have witnessed the results a good 20- 25 times, and i will never recommend it to anyone with an old engine, unless it has been thoroughly cleaned and reconditioned. Enough said, have a good day and cheers for now.
