Sven Jantzon uses Lucas Heavy Duty Oil Stabilizer in 1977 ford maverick 5.0

i recently swapped to synthetic motor oil and allocated a half-litre's volume for lucas' heavy duty oil stabilizer. within the second time i turned the key over and ran the engine, results became immediately apparent. i am deeply satisfied with your product and i enjoy sharing my success and recommending Lucas oil to friends. i plan to soon try a transmission product as well. thanks again
