09KR0058 Posted April 8, 2010 Report Share Posted April 8, 2010 Took the KR to my dealer yesterday for an oil/filter change and tire rotation. Last night I noticed on the invoice that they used 5W20 synthetic instead of the recommended 5W50 that I used the last 2 oil changes. Is this OK?

Actually, if you don't drive it hard, it's probably OK but if it were my KR, I would be using the recommended 5W-50.

Stalwart Posted April 8, 2010 Report Share Posted April 8, 2010 They put in the wrong oil, tell them to fix it at their cost, it is NOT OK and may void the warranty. Link to comment Share on other sites More sharing options...
vapor08GT500 Posted April 8, 2010 Report Share Posted April 8, 2010 No!!! Way to thin...has a customer spin a bearing in his GT500 because of Ford's error putting 5-20 in his car. Took him 6 months to get a new motor. Alex Link to comment Share on other sites More sharing options...
fcettner Posted April 8, 2010 Report Share Posted April 8, 2010 I went to the Ford dealer that I bought my KR from to get the "freebie" first oil change (even though I've changed the oil twice already) at 6K. I asked the tech what oil he would use and he said 5W20. I demanded he use 5W50 because that's what the owners manual references for oil and he said he wasn't sure they stocked 5W50. He checked on it and said they have 5W50. Then we went round and round about using a blend versus full synthetic. I demanded full synthetic because I already use that oil. Anyhow, I made sure dealer was clear on that. Then the tech popped the hood without first unlatching the hood pins..... Wow was I upset and told him so. I won't bring my car there again!!! The lesson is: question the service rep so he is clear on what you want done to your car otherwise, our KR is treated like any other car. Our KR's are the bomb and need our TLC....

09KR0058 Posted April 8, 2010 Author Report Share Posted April 8, 2010 Thanks guys. Just drove it home from the dealer yesterday and haven't been in it today. Called the service rep, got his voicemail and left a message that I'd be coming back tomorrow for the 5W50. The real pisser is that when I got there, I specifically reminded him that I wanted the full synthetic 5W50 Shelby oil, per the owners manual. He said that was what they always use on the KRs. I really should have caught this when I paid the bill. $4.98 per quart could never be the 5W50! Link to comment Share on other sites More sharing options...

i8acobra Posted April 9, 2010 Report Share Posted April 9, 2010 The tech or writer just made a simple mistake. 5W-20 is what the standard Mustang GT uses. If they argue, you'll get better results if you simply point out the mistake rather than getting irate. Just my experience. Link to comment Share on other sites More sharing options...
SicShelby Posted April 9, 2010 Report Share Posted April 9, 2010 I honestly made that mistake MYSELF when I went to do my first oil change - I bought the oil and took it to the dealership because I wanted the Mobile1. Good thing they corrected me! Link to comment Share on other sites More sharing options...
6-Speed Posted April 9, 2010 Report Share Posted April 9, 2010 I declined my free oil change and choose to do it my self ... it's always done correctly. Does the KR oil cap indicate the oil weight like the stock GT500 cap? Link to comment Share on other sites More sharing options...
FENCEKR Posted April 9, 2010 Report Share Posted April 9, 2010 Just my .02 but these are special cars find a service guy who knows and respects it.In San Diego,El Cajon ford has such a guy ,has his own bay and no one in the yard will move it but him and it will stay in the bay until you arrive to pick it up.KRs deserve it.Just bought 2qt after a trip to vegas $20.Yes the oil type is on the cap.

Went back today and they changed the oil & filter for free. I've been happy with them and this was just a screw-up on the tech's part. My service adviser reamed the tech a new one.

steve-s Posted April 10, 2010 Report Share Posted April 10, 2010 Took the KR to my dealer yesterday for an oil/filter change and tire rotation. Last night I noticed on the invoice that they used 5W20 synthetic instead of the recommended 5W50 that I used the last 2 oil changes. Is this OK? Goes to prove, no doubt, can't trust "even" the dealership AND IT SAYS RIGHT ON THE OIL FILL CAP 5/50. Had the same experience with my 09 V.W. Jetta diesel which takes a V.W. 507 oil and the service writer frigging argued with me about it. Called in the Service Mgr. and he told the service writer, he was wrong. Made them let me see the tech. putting in the oil. Either these people are brain dead or just don't give a crap. Probably the latter. My GT500, I bring to a friend of mine that has a auto repair shop and bring my own oil and filter. SAS Link to comment Share on other sites More sharing options...
6-Speed Posted April 10, 2010 Report Share Posted April 10, 2010 Seems like every month I come across one or two folks posting about having the wrong oil put in their motor. Link to comment Share on other sites More sharing options...
FiaCobra Posted April 12, 2010 Report Share Posted April 12, 2010 Hence the reason I do my own maintenance. Did my 1st oil change today on the KR at 600 miles even. Link to comment Share on other sites More sharing options...
shel-b001 Posted April 12, 2010 Report Share Posted April 12, 2010 I prefer to do my own oil changes & make sure no oil is spilled on the frame or any where else when draining & reomo ving the filter. When I`am done I know its done right & the oil level is right. Link to comment Share on other sites More sharing options...
mark289 Posted October 18, 2010 Report Share Posted October 18, 2010 I've never had my oil changed by anyone else on any Mustang I have owned. However, I was in a hurry before a trip last week and decided to just stop by the local Ford dealer for an oil change. I called beforehand to make sure they had 5W50 in stock. Dropped off the car, reminding them it takes 5W50. Came back a little while later and all the paperwork indicated 5W20!! They drained the old oil and changed the filter again in front of me, but still kinda rattles me they would make that mistake?? Link to comment Share on other sites More sharing options...
08KR525 Posted October 18, 2010 Report Share Posted October 18, 2010 You would think the tech. would catch the mistake when he started to put the new oil in. Particularly, since they have to remove the fill cap and it says what oil the engine requires right on it. I've got vehicles from both Ford and GM and they all have it on their fill caps. This is why I do my maintenance. That and I've heard and seen how they "test" drive the vehicles. I'll never understand how people don't respect other peoples property.

08KR525 Posted October 18, 2010 Report Share Posted October 18, 2010 Just curious, does a GT even hold the same amount of oil? I figure it would probably take 5qts. with a filter. Link to comment Share on other sites More sharing options...
oldlugs Posted October 18, 2010 Report Share Posted October 18, 2010 The guy changing your oil at the dealerships will often NOT be their most experienced. That's where the new guys start out, after advancing from being a lot boy doing car washes. You generally don't have your $25 per hour highly trained technician doing oil changes, unless he already has the car in his bay for other work.
