STP Racing History
What does “STP” stand for?
“STP” stands for Scientifically Treated Petroleum. Back in 1954, our only product was STP Oil Treatment.
Are STP products safe for my car?
Yes. All of the STP products have been extensively tested and are safe for use in all cars. Always remember to follow the usage recommendations, which are clearly indicated on the label.
Can I use STP products in my new car?
Yes. STP products can be used in vehicles of any age.
Are STP products safe for diesel engine systems?
STP has specially designed products for diesel engines, which have been labeled as diesel products. They have been thoroughly tested and evaluated in specific diesel applications to demonstrate their ability to help improve specific performance attributes of diesel engines and fuels.
How much do I use?
All STP products are individually labeled for dose and treatment intervals.
Can I use STP additives with other products?
STP products are completely compatible with all other standard fuel and lubricant additives that are intended for similar use. However, mixing fuel or lubricant additives is not recommended, nor should it be necessary.
Can I use more than is “recommended”?
No. The products have been formulated to work best at the recommended treatment rate.
Are STP products safe to use through a vacuum line?
We do not advise putting STP products through a vacuum line.
Is STP still involved with racing?
Yes, we still have a relationship with Richard Petty Motorsports, the longest affiliation of its kind in NASCAR® history. We’re also the title sponsor of the STP 500 at Martinsville Speedway in the Spring. Follow us on Twitter: @STPracing.
