| 13 Reasons Home Oil Changes Are Superior IMO © Derrick Garbell 2012 | ||||||
| home | ||||||
| 1 | cost Å $19; savings of Å$24 allows twice as many changes for less cost than single commercial dealer or quicklube outlet | |||||
| 2 | cold drain = assures maximum purge of dirty oil due to overnight drip to pan | |||||
| 3 | correct, major, consistent brand oil is best for engine | |||||
| 4 | proper oil weight assured | |||||
| 5 | correct choice of proper oil weight | |||||
| 6 | precise oil fill quantity | |||||
| 7 | OEM oil filter = highest quality & assurance of not re-releasing collected pollutants | |||||
| 8 | drain plug gasket replaced | |||||
| 9 | drain plug: never overtighten, undertighten or cross thread | |||||
| 10 | oil filter: never overtighten or leave prior o-ring | |||||
| 11 | change occurs exactly when we're ready, not even a minute's wait | |||||
| 12 | dumping waste oil at AutoZone, O'Reilly etc. easily combined w/other errand =minor chore | |||||
| 13 | 1-time cost of oil change tools Å$20 = drain pan, dump container, filter wrench | |||||
| dealer or quicklube outlets: greatly inferior by comparison, far more costly | ||||||
| 1 | cost=$43 butapples-to-apples because commercial oil changes do not assure oil: brand/weight/level & OEM filter & drain gasket etc. | |||||
| 2 | change while motor hot leaves several ounces of maximum-dirty & non-lubricating oil still clinging to engine surfaces | |||||
| 3 | "our brand is a premium claims" but very rarely any choice to assure 100% brand continuity; even worse:recycled oil blends now being used | |||||
| 4 | commercial may offer choice of weights, but may not include the one best for your engine; e.g. 10W-30=now rare but needed for our Toyotas | |||||
| 5 | even if shop has correct & ideal weight, lube jockeys rush & may choose wrong weight (earn bonuses for volume of changes) | |||||
| 6 | lube jockeys rush & overfill or underfill --> 3,000 miles of insufficient or improper lubrication! | |||||
| 7 | Fram & Purolator grade filters are low performance & filter less pollutants, eventually release dirt back into motor | |||||
| 8 | no quicklube replacement of drain plug gasket, yet gasket good for max 2 cycles, then start dripping > mechanic then over-tightens plug | |||||
| 9 | drain plug: rare but possible overtighten, undertighten or cross thread; even a single instance can be disastrous | |||||
| 10 | oil filter: often overtightened; greater chance of rushing & leave prior o-ring; doubled o-ring gaskets leak catastrophically | |||||
| 11 | almost always some wait; at Walmart (=best price & choice of oils) usually = 90 min > 2 hrs | |||||
| 12 | not a factor, but this minor benefit more than erased in #11) time spent | |||||
| 13 | no tools cost | |||||
