Open All
+ If I already use Chevron, Texaco or Caltex with Techron fuel, do I need to use Techron Concentrate Plus as well?

If you are using a high-quality gasoline such as Chevron, Texaco or Caltex with Techron exclusively, you do not need Techron Concentrate Plus. However, if you occasionally fill up with lower quality gasoline, Techron Concentrate Plus can help clean up deposits that can form over time.  In addition, if you have an engine that is sensitive to deposit formation, or if your vehicle is regularly used under severe conditions, you may benefit from using Techron Concentrate Plus.

Open All
+ How does Techron Concentrate Plus compare with aftermarket additives?

Techron Concentrate Plus is proven to be superior to other aftermarket additives thanks to its significant amount of detergent that helps protect vital engine components.  Every year, competitor products are purchased by Chevron and broken down to their molecular level to be analyzed for their contents. Competitor products either completely lack or have very little of these important detergents that can remove harmful engine deposits. 

Open All
+ How often should Techron Concentrate Plus be used?

Techron Concentrate Plus should be used every 3,000 miles or every oil change. 

Open All
+ Can a full bottle of Techron Concentrate Plus be used in smaller fuel tanks?

If Techron Concentrate Plus is used in smaller displacement engines, such as a motorcycle, you should not use the whole bottle. We recommend one ounce of Techron Concentrate Plus for every gallon of fuel.

Open All
+ My car is knocking and pinging. What is causing this? Can Techron Concentrate Plus help?

Knocking and pinging is generally caused by improper combustion in your engine, called “auto-ignition.” Increases in engine load, temperature, compression, spark-advance, air-fuel ratio and combustion chamber depositis all contribute to the tendency for an engine to knock.  Using higher-octane gasoline reduces an engine's tendency to knock.  If excessive combustion chamber deposits are contributing to the knocking problem, you may benefit from adding a bottle of Techron Concentrate Plus to your next tank of gasoline.

Open All
+ What is the difference between Chevron, Texaco or Caltex with Techron at the pump and Techron Concentrate Plus in the bottle?

The principal difference is additive concentration and rate of deposit clean up. Chevron and Texaco gasolines with Techron over multiple fill-ups will help clean deposits on intake valves and minimize harmful combustion chambers deposits. When added to a full tank of gasoline, a bottle of Techron Concentrate Plus results in an additive concentration roughly 10 times stronger than Chevron and Texaco with Techron. This mega-dose of Techron provides a much quicker clean up of intake valve deposits left by lower quality gasolines. In addition, the high concentration of Techron reduces combustion chamber deposits, which can help eliminate deposit-related engine knock or power loss.

Open All
+ Is Techron just a more diluted version of Techron Concentrate Plus?

No. While both use a polyetheramine-based chemistry, each is optimized for its particular application. Chevron, Texaco and Caltex with Techron helps clean engine deposits left by low quality gasolines and helps keep engines clean through regular use, while Techron Concentrate Plus provides a quicker clean up of deposits left by lower quality gasoline through higher additive dose optimized for fast cleanup.
