Cosmos36 Posted November 30, 2015 Report Share Posted November 30, 2015 An inquiry about the recommended 15 minute waiting period involved in 2.7 engine oil/filter changes arose recently on a F-150 forum that deserves some attention, not only for the DIY types but for owners who have their MKXs serviced at dealers, or especially, those who may use retail vendors such as 'Iffy Lube', etc. Check out: www.edmunds.com/ford/f-150/2015/long-term-road-test/2015-ford-f-150-ecoboost-v6-makes-you-wait.html According to the above source, dealer techs have been informed of the proper procedure via a Special Service Memo (SSM). However, at vendors I have observed vehicles being drained of oil within 2-3 minutes after engine shutdown, with drain plugs being reinserted while dirty oil was still draining (albeit slowly) from the engine. In the case of a 2.7 engine, I wonder how much dirty oil remained in the galleries in a hurried drain procedure such as I have noted...and, how much of an oil overfill (dirty+clean) could be occurring? IMO, 2.7 owners should be aware & cautious. Southerngravy 1 Quote Link to comment Share on other sites More sharing options...
Cosmos36 Posted December 5, 2015 Author Report Share Posted December 5, 2015 For the DIY oil changers, there is a recent video (posted November 13, only viewed 21 times to date) at https://www.youtube.com/watch?v=RD0UoR626oY relating to the 2.7 engine. It is especially informative for those searching for an under hood view of the canister filter location, i.e. rear, passenger side corner of engine partially hidden by large, black wrapped wiring harness.

Adam Posted December 6, 2015 Report Share Posted December 6, 2015 Thanks for the info. I may attempt to do my own oil changes again with my X. Haven't done that since 2007 or so when I had a Jeep Cherokee and could do oil changes without the need for jack stands. I like that the engine cover has a cut-out for the filter housing so you don't have to pry it off, but the black wire bundle right in the way left me scratching my head. I also wonder how much old oil is left in the engine/turbos/piping after an oil change on the 2.7. Probably best to err on the side of caution with the intervals and use high quality materials.

Cosmos36 Posted December 6, 2015 Author Report Share Posted December 6, 2015 (edited) While attempting to differentiate front from back of the MKX's 2.7 engine, I'll have to confess that the transverse engine layout had me perplexed for awhile since all of my prior inspections of that engine were on display stands or installed in F150 trucks. In those scenarios, the front of the engine is clearly identified by the integrated front cover, filter canister, oil cooler, etc. Only recently did I take the time to locate the filter canister hidden behind/below the wiring harness and confirm that the front of the engine is on the passenger side of the vehicle. I had previously assumed that the engine cover had to be removed to access the canister. Next, I need to inspect the underside of the engine to check out access to the plastic drain plug (note: I hate winter cold for such chores). A cursory inspection indicates that the front underside of the MKX is covered by a large aerodynamic cover. I have ample supplies of both Mobil 1 & Quaker State UD 5W-30 synthetic oils meeting the HTO-06 spec for the MKX oil changes. Locally, filters are available only at Ford dealers. That's OK as I prefer OEM filters. Edited December 6, 2015 by Cosmos36 Quote Link to comment Share on other sites More sharing options...
