Suitable Oils for Our Triumphs - flat tappet (lifter)
engines
From the folks at Castrol:
"This question is coming up more and more, Anyhow,
engines such as this that use flat tappets could be sensitive
to reduced levels of Phosphorous in oil formulations, it appears
that 0.1% is about the cut off point, so oils for flat tappets
should contain .1%. Phos has been steadily going down as
the amount of ZDDP has been reduced to ensure compatibility with
exhaust after treatment From our range the following are higher
than 0.1%
