  • Oil & Gas

    I have a 1950 Champion. Been hearing a lot about ZDDP and there are additives on the market. What is the opinion of this stuff? Should we use it in our older engines?

    Also, what octane gas is suitable?

    Thanks

    87 octane is quite acceptable.

    A search (upper right corner of this window) will show many threads about oils. The quick and dirty explanation is that a year or two ago, the oil companies, realizing that all modern engines have roller lifters stopped putting ZDDP additive in their oils. This additive lubricates the cam lobe as it wipes across the flat lifters. Without it, our cam lobes will shortly wear away.

    Do a search for 'Oil Additives' or 'ZDDP', study the subject then decide what to do to keep your '50 Champion on the road and happy.

      Even the old President straight eights run well on 87 but, Yes, we do need to anticipate replacing the lubricants our older engines need. These are being eliminated from modern oils because the roller rockers don't need them and they can foul the catalytic converters in modern vehicles. Ruin your engine and you can take advantage of the cash for clunkers rebate.[V]

      I'm adding ZDDP, available from many of our great vendors.
