You will need bottle(s) for a full Revive treatment.
Always start with a cold engine, unclip the intake pipe after the airfilter & MAF sensor. Spray Revive in 3 doses of 250 ml into the intake, 1st with the engine running at 2200 RPM.
Next at 1800 RPM, stop the engine for 3 minutes.
Re-start the engine then finally at 2000 RPM.
Keep the engine running for a few more minutes until the Revive has worked out of the system. Take the vehicle for a brisk drive of about 20 minutes, exercising engine components and completing the Revive treatment. The Revive cleaning process can be performed before a service, this allows the vehicle to be checked over and filled with clean oil.
