Here is some correspondence I had with Redline about thier calcium package. Read up from the bottom. XXX, Calcium has been and continues to be the most effective additive for cleanliness and wear protection. It is highly unlikely the industry will move away from it as an additive but engine manufacturers will learn to deal with LSPI. There are a number of factors that can impact LSPI, unknown how our oil, the base stock and additives used would compare to others.

On the lubricant side, the most noticeable impact has been from the detergent chemistry. Oils with higher concentrations of calcium, which is found in many detergent systems, have been shown to increase the frequency of LSPI. The exact chemistry of the detergent is less important to LSPI than the calcium content. Conversely, magnesium-based detergents do not seem to promote LSPI. Although reducing calcium may seem like a solution to control LSPI, there may be other performance tradeoffs to consider. In addition there are other additives that can also help reduce LSPI events. This provides an opportunity to formulate for robust LSPI performance, while maintaining the level of detergency needed to help keep engines clean and neutralize acids generated during combustion. Aside from the detergent system, there are many other additive and lubricant compositions that can influence LSPI. Molybdenum compounds, for example, not only provide frictional benefits, but also have been shown to decrease LSPI when used at high levels. Base oils also affect LSPI events. Both the quality of the base stock (i.e. Group II versus Group III) and the viscosity can have secondary effects on LSPI. The effect on LSPI from these other lubricant aspects are not as significant as the detergent system, but can shift the LSPI frequency in oils that are more prone to LSPI.

Thank you for contacting Red Line Oil, I am not aware of any specific direct corelation between calcium and intake valve deposits in DI engines, though I will speak with our Chemist. The information that I have seen seems to indicate the intake deposits have more to do with the specific engine, it’s design, the EGR and PCV level and likely other factors. Using our SI-1 Complete Fuel System Cleaner on a continious basis in direct injection engine will help control injector and combustion chamber deposits, the detergents can remaining active through combustion which helps control EGR and intake valve deposits.

Comments: Question: I have been a user of Redline products for 20 years. I now have two brand new Ford F 150 pickups, both with the 2.7 Ecoboost, which is Direct Injected turbo engine. One of the problems with direct injected engines, is that calcium additives can exacerbate intake and piston deposits, particularly during (and possibly causing) Low Speed Pre Ignition(LSPI). Redline Oil has a pretty stout calcium package. Any thoughts on this?
