AU cat converters and PULP

After the recent thread about fuel quality differences between brands i wonder if any AU owners have had trouble with catalytic converters with PULP fuel

Have been thinking about adding $10 dollars of PULP with Unleaded to boost octane rating but am cautios after blowing a converter while using PULP in another car a few years back.
Anyone know how much a converter is for an AU?

g'day matt,

I dont know how much a factory one is, but a high flow one will cost around $200 (give or take, depending on the place), I wouldnt think you would have a problem though!

most aftermarket high flow cats have a warranty on them any way

cheers

How many miles did the "cat" have on it when it blew, they are only designed and warranted to work for 100,000km, after that they tend to melt down or break apart..Had this happen on an Old sigma (86) took converter apart and the whole of the honeycomb structure had melted, no wonder it sounds lika it had a banana up its arse....

Run Forrest , Run.......

How interesting, it happened when my car had 105,000 km's on it so i guess the PULP probably had nothing to do with it
Some mechanics say you shouldn't use PULP with cat's and some say otherwise.

Thanks for the info, i will make sure i check out and replace if neccessary the converter when the AU hits 90,000

I wouldn't listen to a mech that said that about pulp! The SS 5:7Commodore [10: 1 compression] is supposed[recomended] to run on it as most B.M.W's. Including the 250 KW T3..Besides in Japan they use higher octane ratings..Depends on how management system works the spark needs to be advanced to take full advantage of the slower burn of higher octane..

Don't be afraid to try something new. Remember, amateurs built the Ark...Professionals built the Titanic!

Adding $10 of PULP will do nothing. The chemistry between the two types of fuel is significantly different. It takes three tanks of PULP to flush the standard shite out of the system. If you're going to use it use it properly and FILL UP!
