Lucas makes a high zinc oil in 10W-30 and 10W-40 weights. Classic Car Club of America sells a classic car motor oil with high zinc content in 15W-40 weight. I have used the CCCA oil but not the Lucas. I bought a supply of Lucas 10W-40 through Amazon and plan on using it in my 55 Dodge 270 Hemi engine for its next oil change.
