xtopher Posted March 8, 2003 Posted March 8, 2003 Dear anyone, My new C5 HDi 110 apparently takes semi-synthetic oil Total Quartz 7000 (I am told it does not have a particle filter so the 7000 is ok - see maintenance guide) . Just been to Halfords this morning -don't do it. I expect Cit franchise will charge an arm and a leg - is there an easily available equivalent bearing in mind I want to run this car properly and for a long time. I assume it has to 'Diesel oil'? xtopher Quote
Kevin Posted March 9, 2003 Posted March 9, 2003 The Total 7000 oil is a regular semi synthetic oil, not a special one for diesels only. Total 9000 5/40 is a full synthetic and is also recommended for the C5 110 HDi in the handbook. You can put in Halfords (made by ESSO) own 5/30 fully synthetic oil for topping up. If you look on the back of the pack, you will see a code for the rating of the oil for diesel engines. Currently most oils are up to CF. The rating for petrol engines would be something like SG. MOBIL do a MOBIL 1 oil specifically for diesels, but it costs an arm and a leg and comes in 1 and 4 litre containers. Quote
xtopher Posted March 13, 2003 Author Posted March 13, 2003 Thanks Kevin very helpful, My handbook mentions particle filters which have affects whether 7000 or 9000 is used. Apparently my C5 does NOT have the filter so 7000 can be used. However it is not apparent from any of the cars info books whether or not a filter is fitted - I have taken the Franchise dealers advice! Xtopher Quote
Kevin Posted March 17, 2003 Posted March 17, 2003 In anticipation of my C5 using a bit of oil during the running in period, I today invested £10.95 at Halfords on 1 litre of MOBIL1 0/40w turbo diesel synthetic oil. I will give the car an oil change at 6,000 miles. Probably take it to Chessington Tyres in Eastbourne. £28.95 for a sumpful of MOBIL 10/40 semi synthetic and a replacement oil filter. Quote
bencowell Posted March 20, 2003 Posted March 20, 2003 NO NO NO Don't get the oil changed just anywhere, make sure you get an original Citroen filter put on or else the dealer will notice and may invalidate your warranty. Eurocarparts will sell you a cheaper identical filter (might be in a Peugeot box though!) Make sure the oil is to the spec mentioned in the handbook, both the 10w40 bit and the ACEA A3/B3 or whatever. Ben Quote
car-mark Posted May 26, 2003 Posted May 26, 2003 Check out the valvoline web page this is a good oil company that I use for my garage. Loads of information on the type of oil and grade to use car-mark Quote
madman Posted June 2, 2003 Posted June 2, 2003 I use Total Quartz 9000 diesel in my C3 HDI. I normally buy a few cans when I am in France as it is much cheaper. I will only use fully synthetic diesel specific oil but will use any manufacturer. Bob T Quote
Kevin Posted June 9, 2003 Posted June 9, 2003 I gave my C5 2.0 HDi estate a birthday a couple of weeks ago and ran it into Halfords for an oil change. The reason for this was that I noticed from 5,500 miles on a discernable change in the amount of noise produced by the engine. It sounded far more 'dieselly' and because my engine is Superchipped, probably the oil is getting more of a workout. So a sumpful of Castrol 10/40 GTD Maganatec now in the engine and boy what a difference. Engine immediately sounded more muted and 'cushioned' and has continued to stay that way after 1,500 miles of fast driving. However there has been a downside. This oil has definately caused more 'drag' in the engine. Top end perfomance is down a bit and the fuel economy reduced by 5%. Averages 38 mpg instead of 40 +. I would say that the 2.0 HDi is better suited to a thin oil like the 5/40 Total 9000. I will specify that oil at the next service and being a full synthetic, I probably will not need to change it in-between services. Cost of oil change at Halfords was £38.00, local dealer in Eastbourne wanted £52!! Here in France, first service is only 85 Euros at local Citroen service centre. Quote
xtopher Posted June 12, 2003 Author Posted June 12, 2003 Useful info Kevin many thanks. I was only thinking the same the other day - (after 6500 miles) does my engine sound more dieselly! The trouble is after a while one gets paranoid about the slightest new noise,rattle etc once one is tuned into the cars dynamics! One question - does superchipping invalidate your warranty?

Kevin Posted June 14, 2003 Posted June 14, 2003 I noticed recently that Rover dealers are advertising a power enhancement for 75 owners who have diesel engined cars. For £400 they will make a software adjustment to the engine management system to give an extra 25 bhp plus torque, but I can't remember how many llbs extra you get though. It doesn't effect a Rover's warranty....... Quote
