Rams 0 Posted June 16, 2003 The oil on my car seems to be really hot, when I took the cap off you could see the heat like a small heat wave. I know they run hot but could I have any problems? My temp on the MFA was reading on the motorway, now I am just trying to remember but I think it was around 128 degrees, I could be wrong, the water temp was just up from 70 /80 so that seemed spot on. I would just like to know if there are any possibilities why that could be, or how can I tell if the oilc cooler isnt working properly without chaging it?

Scott 0 Posted June 16, 2003 Sounds pretty hot at 128deg C.... Im running at a constant 116degC at 80mph.... Quote Share this post Link to post Share on other sites
Rams 0 Posted June 16, 2003 In town earlier it was 96 degrees, does that sound about rite scott? Quote Share this post Link to post Share on other sites

Henny 0 Posted June 16, 2003 Sounds pretty hot at 128deg C.... Im running at a constant 116degC at 80mph.... Umm, I know yours is not a G60, but I did 400 miles today at an average of 80mph... Oil temp 122 :shock: Water temp just under 100 :? I slowed down to 70 from about 90 and the temps plummeted almost instantly! (102/80!) :roll: :lol: I think she needs a service! :roll: I think 128 is getting to the worrying side of hot, may be worth getting an oil change done... :?

Rams 0 Posted June 16, 2003 Sorry, it wasnt that high, thanks for reminding me about an oilchange though, I will do it over the weekend! I have been using GTX Magnatec, can you recommend anything better for the VR? Quote Share this post Link to post Share on other sites
Scott 0 Posted June 16, 2003 128 deg C does sound very hot for a G60 would have thought..... Oil temps do increase when accelerating and when at constant speed and the water comes down to around 90degC.... then when you park up and idle the oil temp will fall to about 100degC and the water will go up to 100 - 105 degC... This is because the water system is acting as a heat exchange for the oil hence the oil cools... Another good reason why after a hot run its good to leave the car idling for 30-60 secs so cooled fresh oil gets around the engine before switching off.

Henny 0 Posted June 16, 2003 GTX Magnetec is pretty much the best for the VR6.... Quantum Silver is ok too. I heard that Porsche dealers stopped using Magnetec as it was causing the cars to suffer from low oil pressure... I stopped using it straight after that and only use genuine Quantum silver or Vauxhall semi-synthetic (I get it free from a mate and it's good stuff, even though it's Vauxhall! :lol: ) This was a few years ago mind, but I'd still keep an eye on your oil pressure though if you're using Magnatec.... :?

Kevin Bacon 5 Posted June 16, 2003 If you consider how close the cylinders are to eachother on a VR6, it's no wonder it runs hot. A W12 must generate enough heat to warm a small village during the Winter! When I first picked up my VR, it was running at 114-118 degrees cruising at 80mph, which is too hot for my liking. I installed a Mocal oil cooler and it sits at 96-98 at the same speed, and 102-104 at a constant 100mph, which is more like it. Kev 94 VR6 Quote Share this post Link to post Share on other sites

Kevin Bacon 5 Posted June 16, 2003 Definitely worth doing mate. It's so effective, I rarely bother to check my oil temp anymore, even in this heat! Bear in mind you won't undercool your oil since you retain the stock heat exchanger and the Mocal only kicks in when it's valve opens at 80 degrees. If in the winter you feel it's undercooling, you can simply block the Mocal with some tinfoil or something, although from past experience, this won't be required. VR6s lose a bit of power when they get really hot, so there's another reason for installing one :D Kev 94 VR6 Quote Share this post Link to post Share on other sites

Kevin Bacon 5 Posted June 16, 2003 I used to use Vauxhall oil in my *cough* Cavalier and it seeped out of most of the seals, so I put Quantum silver in it and never saw the problem again! I even used to use it in my BMWs! It's good stuff. Not sure who makes it, probably one of the big 4 - Shell, Mobil, Esso or Fina. It's all pretty much the same stuff but each manufacturer endorses a particular oil for their engines. In our case, look for VW501.1 classification and you'll be OK.

I will order one now on the fone if anyone can give me details? http://www.thinkauto.com You need a 13 row by 235mm cooler plus a VR6 fitting kit. Let me know when you've got it and I'll advise you how and where to fit it. Cheers Kev 94 VR6 Quote Share this post Link to post Share on other sites
