GT First Service - Check your oil all every week - Ford Forums

DGROMS.com · 07-08-2003, 02:27

Just got my car back from its first free service, and I was presented with a few concerns. It seems my machine has been treated the right way (like it was stolen) and the engine is bedding in fine but the service manager has told me of some serious issues with GT engines using around 7L of oil before there first service. It seems some really smart engineers at FPV decided a full synthetic oil was ok to put in there new vehicles and some people only treating there cars the way the manual says and not actually giving it a bit of a hard time have had to add around 7L of oil. The demo car at the dealership has used 4L of oil and not even done its first service yet.

I was lucky/smart, I check my oil every week and I only found the gauge down to 1/2cm below full last week, which turns out is about 1.5L of oil. The guy said even when they are low on oil he has had no problems with noises ro heat but it means they are not going to perform really well long term, he actually is getting 2 engines replaced by FPV for the people with the worst problems. He has reported mine to FPV as a case report and warned to keep a keen eye on the oil.

My suggestion to all new FPV owners, make sure you either really run the engine in as a performance engine, ie never use cruise control, get it warm and give it a few good hard runs, but not too many, drive it on a nice high speed run early and keep the speed UNEVEN to allow the pistons to work the full length on the stroke to let the engine bed in properly or/and if possible insist on non synthetic oil be put in the car before you take delivery as synthetic oils are bad in new engines OK

Wow cool, you post here too?
Don't let the LS1 brigade hear about this.. eep

The difference here Whitey is that Ford/FPV are acknowledging a problem were Holden/HSV say it is OK for an engine to use 5L of oil between services even with a run in engine after 15000km. Ford have made an error in judement in selecting an oil and I am sure that it will be fixed soon from the factory, the LS1 is just a crap engine and nothing can stop it burning oil, they replace them and replace them, yet it is still not a problem:D

Yeah im past that point now mine used a bit of oil approx 2 litres till 2,500 but it is slowing down now as the ks come up.
I have my own workshop and have found that it is common among hand built engines to use a little oil till the rings bed in but my own opinion as previously stated these engines should not have had Synthetic oil fitted for the first 10,000 km so as to assist a good bed in. Im not changing my oil from what is recomended by FPV even though i want to, so im giving her a good hard drive every so often so as the counter act the slippery synthetic oil. I would strongly recommmend that you not drive your GT/GT-P easy as this will amplify the problem down the track some time.

Has anyone else had this problem?

I pick mine up in about a week and I would appreciate any feedback.

Pick my citric gt up in T minus 12 hours........

Well by what you guys are typing drive it like it was meant to be.
Start as you mean to end.....

Yes I noticed the oil consumption on my GT. I must have used about 3 litres of oil up to my 3000 kay inspection service.

I have only done 4000 now. do you guys think I should change the oil for a mineral base for a while until at least 10,000 or is it too late.

Any coments. I drive it hard all the time though.

I changed mine at 1500 km and then it will be 7,500 and every 7,500 after that.
After extensive discussions with the techos we've given away the Mobil 1 0W40 in favour of a 5W40 Shell Helix (which is a recommended alternative lubricant).

In terms of the running-in procedures, I have a question I'm sure some engineers out there can answer. People seem to make constant reference to giving the engine a bit of a rev to make sure the top part of the cyclinder gets worn-in as much as the bottom part.

I may be a little simplistic here, but the piston is connected to a conrod which is in turn connected to the crankshaft. Surely the length of the piston stroke is the same no matter whether the engine is doing 500rpm or 5,000rpm??? Is it crankshaft flex that causes a slightly longer piston travel at high speeds?

I would have thought that the main reason for giving the engine a rev would be to expand the rings via natural compression loading which would occur when the engine is placed under load, rather than the 'stroke' varying in length????

Not only the case. Whilst what you have said is true also the higher the revs the higher the piston speed. The more force on all the components hence the slightly high stroke under higher revs, also hence the Boss engines in ability to handle high revs due to the intense piston speed which would result with such a long stroke, the stress on the components is huge and you would end up with a big mess.
