QUESTIONS & ANSWERS
Q: Break-in oil bluestreak49er3 years agoI see that they suggest a high zinc oil during break-in. Do you guys have a specific oil that you would suggest?

A: Any properly weighted oil with zinc additive will be fine, we carry the Redline additive if needed or there are many other oils at local auto parts stores that are meant specifically for break in.Nick S. @ RallySport Direct 3 years ago
