Your cart is empty.BG EPR Engine Performance Restoration is a powerhouse of an engine cleaner! It effectively softens, emulsifies and dissolves even the most stubborn fuel gums that clog rings. Engines are operating at higher temperatures than ever before. Combined with prolonged drain intervals and reduced engine cooling, automotive engine oil is under a lot of stress. Continuous thermal and oxidative breakdown contributes to oil thickening, heat retention and deposit formation. These heavy deposits can impede normal piston-ring function; thus reducing fuel economy, lowering power output, and increasing harmful exhaust emissions and oil consumption. BG EPR, PN 109, softens and dissolves hard-to-remove deposits from piston rings in as little as 10 minutes! Properly sealed combustion chambers improve compression and reduce oil dilution through blow-by. BG EPR cleans micro passageways to maintain the critical hydraulic function of components such as valve train actuators and turbochargers. BG EPR restores fuel economy and power and prevents excessive oil loss. Excellent for maintenance of Gasoline Direct Injection engines.

I used this in the fall to clean my VW Tiguan Wolfsburg TFSI 4Motion engine. I was having noises and excessive oil consumption the past two years. This is a great product and after 3000 kms in Canadian fall/winter it did the trick. Less noise and much improved oil consumption. I recommend buying the pack of 4; great value! When flushing the engine do it right. On these TFSI engines you need to change oil every 5000 kms to avoid carbon particles damaging your engine. My car just turned 100,000 kms so going forward i plan to flush every year in the late fall as a winter prep. Also check your spark plugs. I flush the old oil first but kept the oil filter. Then I put cheaper conventional oil (not synthetic) and added ERP to that., ran for 15 min at high idle per recommendations. You can really see the engine cleaning performed from the oil colour. Do this during daytime. Then I flushed this oil out and replaced the oil filter. Finally filled with synthetic oil 5W40 Euro. The car never sounded better. I also recommend checking PCV valve at 100,000 kms or sooner. It will avoid major engine problems and of course unnecessary oil consumption.

I am not one to use oil additives, nor do I believe advertising hype that defies the laws and physics and chemistry. Watched several trusted YouTube videos in which this product seemed to work. I tried it in my 2006 Highlander with 193,000 miles which has seen 5K oil changes since new. The car will burn a quart or less in 5,000 miles if you run it hard--70-80 mph. I added a can to the oil and ran it for 15 minutes after a one mile gentle drive. The first think I noticed upon oil drain is the oil was black and gritty, which is abnormal for this engine. The particulate in the oil appeared to be gritty carbon. I refilled the crankcase with good oil and changed the filter. I didn't think it could run any smoother, but it does. The oil level has not moved in three weeks. This is not unusual because it has not been driven hard. For this SUV with a 2.4, 80 mph is near it's maximum. Time will tell, but so far, the oil is clean and the engine is very smooth, both at idle and under load. My opinion is there is only one place in the oil system that accumulates carbonized oil, and that is between the oil rings and in the ring grooves. There is no other place in the engine that receives that much heat and blow-by. The suspended material was considerable. These engines tend to be sensitive about oil coking in the oil rings, and this product definitely goes to work on it. Update: I used this treatment on my other two vehicles. My 2003 4cyl with 120K miles has been smoking on cold start for 15 years. The cold-start smoking has stopped and not returned in 6 months. My 2017 Tacoma did not show any significant darkening of the oil and there were no changes at 85,000 miles.

Change oil ever 4k full syn on all of our vehicles for the last 20 years or so. Main trailblazer vehicle we owned went over 400k and ran great when sold last Jan. Even still, after I first started using around 2019, lots of yuk comes out after completing. Can feel a noticeable difference in acceleration and performance. Somewhat pricey, but worth it to me experiencing the results.

Very good for washing, but not quite enough to completely clean the rings, at least in my case

I'm a master mechanic and I was introduced to this product at the dealership I worked at. We tested it to make sure it really boosted compression by freeing up the rings on the pistons. Used as directed and it restored compression back to our 2001 Maxima test vehicle. I have also used this product in my Jeep Wrangler JK and JKU to stop the oil consumption. I've used it in my 1990 Civic, 1997 Camry, and 2006 Silverado to clean out sludge from previous owners' neglect and restore compression. This product is by far the best. Better than AC Delco top engine cleaner, Marvel mystery oil, other flushes, etc. The only thing I recommend about this product is the longer you run your engine, the cleaner it will get (e.g. follow directions but run for 30 minutes instead of 10). I also recommend using the MOA product.
