Zinc oil additive Lucas

There has been a lot of confusion in the last few years about the lowering of zinc and phosphorus levels in modern oils and how these lower levels relate to classic and performance engines using standard flat tappet lifters – that is, just about every car built before the Eighties. The concern involves the use of the new lower zinc/phosphorus-content ILSAC (multi-viscosity) oils, readily available on shelves at auto parts stores everywhere, and how compatible they are with these older engines.

When anyone mentions zinc, they are actually referring to zinc dialkyldithiophosphate, a compound invented by Castrol for use in mineral-based oils or zinc di-thiophosphate (ZDTP), which is normally used in synthetic oils. Both have been used as an anti-wear ingredient in engine oil for many years. The zinc and phosphorus ingredients appear to be most effective when they are used together. ZDDP/ZDTP is one of many additives that are put into conventional motor oil to improve its lubrication qualities. Other ingredients such as boron and molybdenum are also added as lubricant enhancers.

What was discovered through oil testing by several engine component manufacturers is that many older engines experience a short period of time during engine start-up where critical lubrication is insufficient between metal-to-metal lubrication points when using modern oils with reduced amounts of ZDDP/ZDTP. These same enhancers unfortunately have their downside: The phosphorus in this compound creates carbon buildup in engine bores and valvetrains, and both compounds can also lead to the early demise of catalytic converters. For this reason, the industry has been phasing out zinc and phosphorus levels since 1994, when the American Petroleum Institute’s SH designation became the industry standard, and levels have been further reduced in each subsequent API rating for engine oils. Manufacturers have tried adding more boron to offset the effects of the reduced zinc and phosphorus levels; however, the dry start protection does not measure up to those using more ZDDP/ZDTP. This has opened up a whole new market for zinc/phosphorus additives for oil and many camshaft and engine manufacturers now recommend that an additive be used in initial break-in and for regular use.

Popular Q&A

Lucas oil additive?

they work great,they are not a cure for mechanical breakdown but do offer more protection.lucas was originally designed for heavy truck use.
i have used these products for many years and never had a problem.
as for cold starts the lucas stays on the parts to protect them till oil gets to them.
as an example at 20 below 10w30 can take up to 3 minutes to lube the top end were as 5w30 takes less than a minute,this time period is where lucas adds protection
