Engine and Transmission Tech

For anyone interested, here's a link to an engine oil article. I find it to be very technical and informative; happy reading!

I just bought Castrol synthetic with "Titanium" ! Is it lighter ? Will my valves stop floating ? Will my motor still miss boron and zink ? Does it need fem iron once amonth ? I just love all the new buzz words, but sometimes they seem a little confusing. roverman.

Here's something less confusing; simple test and result. It surprised me that Red Line did so poorly being the second most expensive of the test......
Best buy for the money and result: "Valvoline Durablend"

Impressive results from the Royal Purple Racing oil. Wonder how this relates to zinc content for lifter wear protection?

Jim, judging by the scar left from the test I would assume that flat tappets would be in good hands. This whole oil thing is changing too often as manufacturers have to answer to the tree huggers. More and more replacement additives are being developed to not only satisfy the EPA people but, also the MPG standards. Unfortunately, we have to resort paying high dollar for racing oil in order to protect our investment. I personally always recommend a partial synthetic oil over a full synthetic.

I am also partial to Brad Penn 10W-30 (Penn Grade 1) which is basically the old Kendall racing brand. It is suitable for either racing or street use. It also has higher level of Zinc for flat tappets. I don't believe that dropping $11.00 a quart for oil in a mild street engine is necessary but, it would be in something like you're building in your MGB. With all of the money these oil companies make, you would think that they would put out a simple chart to help the gear heads chose a proper oil design for his needs.

I guess that'd be too simple. I used Joe Gibbs for break-in oil in the 455 and in my 340 but haven't really made a decision beyond that, though I di buy a dozen tubes of ZDDP additive. Wonder what adding that to one of the better oils would do?
