8/6/2023 0 Comments Quicky flush![]() This practice makes sense and is recommended in some SAE manual and in the latest Mobil literature I saw where flushing was implied prior to use of the Mobil 1 EP.Īnother time I do a quickie flush is after ARX cleaning with the same filter but before the formal Rinse Phase and new filter. A flush, to me, is just an intermediate oil to leave the engine internals clean.er for the top-quality oil that's intended for regular service, next fill. I'd be more inclined to flush a restored Porsche or Alfa than Grannie's Valiant. Another factor is budget and value of the car. An hour at home drains better than 30 seconds at a Quickie lube. This all partly depends on how long your last oci was and how long you are inclined to drain your oil time-wise. It depends on the level contamination you are willing to tolerate. To flush or not to flush, that is the question. If the newly installed synthetic motor oil becomes very dark (except for diesels) after only a few hundred miles, chances are the engine was still dirty upon changing to a synthetic motor oil and an engine flush and/or another oil change is warranted. Furthermore, dirty oil has a tendency to burn more than clean oil resulting in an increase in oil consumption. Without the engine flush a synthetic motor oil will use its inherit high detergency properties to clean a dirty engine resulting in a high volume of dirty oil being trapped in the oil filter. regular and frequent changes of dinosaur (petroleum) oil), you simply drain out the old and add the new synthetic lubricant with a fresh filter.įor vehicles with more than 60,000 miles or one with a questionable maintenance background, you may wish to clean the engine with an engine flush before installing the new synthetic motor oil. You do not need to flush your engine prior to changing to Mobil 1 Extended Performanceįrom the Pennzoil website: Synthetic motor oils can be used occasionally or regularly.ĭo you REALLY think Pennzoil would make that statement if you had to flush your engine every time you switched either way?įor a mechanically sound engine with less than 60,000 miles, and which has been well maintained (i.e. I will bet if you ask all the major oil companies if you need to flush (in order to make the switch), you will get an overwhelming "No, No, No" I'll do a quick check but I think you are wasting time and money, unless you just want to clean the engine before you put in syn.įrom the Mobil1 website FAQ: (I believe they intended this question to apply to all versions of M1 as it is not repeated in the "regular M1" section.)ĭo I need to flush my engine before switching to Mobil 1 Extended Performance? I initially interpreted your question as meaning, "Do I need to do a special flush in order to change to syn oil?" If that is what you are asking, "no, you don't." If you meant a flush for cleaning purposes, you can if you want. The best way to "flush" your engine is to resort to using AutoRx or use high detergency motor oil such as HDEO or XD-3.ĭo it the gentle way, or none at all. Next thing you know: 5 miles down the road after you performed a 10 min flush, your oil light came on and you spun a bearing or 2 due to oil starvation (good luck try claiming warranty with that!) Worse yet: harsh solvent has the tendency to break loose large chunks of sludge or carbonacious debris during the cleaning process and when those debris ended up in your sump pan, it will clog your oil pickup screen and starve your lubrication system to death. The swelling will definitely ruin the seals no matter how short the flush duration is. Ordinary "flushing" calls for harsh solvents (kerosene, paint thinner or Stoddard sovents,etc) are extremely hard on engine seals such as crank/cam seals, valve guide seals,etc. ![]() Naaah! I wouldn't "flush" the engine with anything but the following (if you really want to "flush" it, which I pretty much doubt the need for that): AutoRx, or HDEO/XD-3 oils.
