Gonna service my S70R at the weekend. Whats the best engine oil to use? Its a '98 automatic and done 160'000. I'm gonna give it an engine flush aswell, but want some good oil in it. Suggestions? I'm gonna change the gearbox fluid aswell I think and have I got to get the volvo stuff from the dealers? Have I heard right that if you use aftermarket gearbox fluid it could knacker the gearbox?
I use Castrol Magnatec and it works well in both of our T5s, we change the oil every 6000m or 6 months. As for the gearbox Volvo Auto fluid if you want to go for the recommended, but the are other oils. Have a look on here http://www.revolutionoil.co.uk/lubricants/transmission.php. They have some info in Dexron III Volvo's recommended Autobox fluid was Dexron IIE (or Ford Mercon) when your car rolled off the line. This was upgraded to Dexron III which is backwards compatible with Dexron IIE So if you look around for a good quality Dexron III you should be OK. You might like to ask RUFE for some advice if you want more info.
At that milage I would not flush the engine, the carbon/metal deposits that have built up it otherwise unaccessable places will be removed by the flushing detergents and in particular the crank shaft float. I would just refill with Castrol Magnatec - T5s love it!
I always use Mobil Super S its about £30 a bottle and the car purrs when she is filled up with it. Upon failing that castrol magnatec anyday. I always find http://www.opieoils.co.uk/ quite competitive if you need a supplier.
i use millers oil runs sweet on that
went for mobil super s. Sounds really quiet and purrs now :)

well i thought I'd go for something I'd never tried before. And like I said it seems to be sweet!

[quote=smithness;313499]i use millers oil runs sweet on that[/quote] Use this in the kit as it is extremely good with high oil temps but would only use a standard oil like Magnatec in in the tintop
Mobil 1 or equiv is great for a new or nearly new engine - used it in my cosworth from new and carried on using when modified up to 375bhp with no problem but to put it in an engine that has done 160k that also has had a higher sae oil in before is sure going to rattle. If the engine had always been run on a fully synthetic oil of around 5sae then great but this engine as I understand it has not!
mobil super s is semi syth. 10-40w. It doesn't sound noisy, it sounds much quieter than before?! How would flushing the engine block an oil return or cause damage? I've never heard that before?
I'm talking about the fully synthitic Mobil 1 or equiv that is 5 sae. If an engine has been run for say 100k on a none synthetic oil and one that does not have a high detergent present then over time carbon and other deposits build up at the main bearings of the crank shaft [the design of the crank requiring a small amount of end float] If after 100k those deposits are removed then the crank will now have more lateral movement, we are only looking at maybe a thou or two but this now means that the big end bearings that have formed their niche over time will now have more lateral movement to the con rods then to the small ends etc etc. This whole process having a loosening effect. I have seen it, measured it and listened to it on a lot of engines. I am not saying that this relates to this particular engine or not because the history is not known but just in case I would not use a fully synthetic oil on a 160k engine of unknown origin.
cheers, yeah I wouldn't use a semi synth oil on an older engine. Good bit of info that and something to take into account :)
Anything well regarded and 10w40 semi. My mechanic always recommended semi over fully-synth for the T5s, not sure why though. Anyway, he always used 10w40 semi and I never had a problem at all, the engine had just under 180k when I sold the car and it was running perfectly.
