Weirdy Posted February 8, 2005 Share Posted February 8, 2005 Dave from Hyperion said he gets his locally if he needs it, somewhere in Halstead, closer than Caterham in Dartford, but still it got me thinking..... Anyone else get thiers locally fairly cheap.... Minty burns about a litre every 500 miles..... Weirdy Its not the winning thats important, its the taking them apart.......

Bare Posted February 8, 2005 Share Posted February 8, 2005 Geee.. Mebe you might consider something with a wee bit more viscosity than water then :-) Link to comment Share on other sites More sharing options...
Weirdy Posted February 8, 2005 Author Share Posted February 8, 2005 Bare Yeah I use the 0-50w, its the best at power band type pressures in the engine, and keeps the engine cooler..... so anything more than sarcasm to my question 😬 Weirdy Its not the winning thats important, its the taking them apart.......

Jason Plato Posted February 8, 2005 Share Posted February 8, 2005 I would consider stripping the engine down with that consumption . Link to comment Share on other sites More sharing options...

Mr Locust Posted February 8, 2005 Share Posted February 8, 2005 The last car I had with that kind of oil consumption without blowing a hose off the oil cooler was an Austin Princess. Ian Green and Silver Roadsport 😬 Link to comment Share on other sites More sharing options...
Weirdy Posted February 8, 2005 Author Share Posted February 8, 2005 Caterham reckon the VHPD burns a litre every 1k miles, the way I drive her it does feel like more, I do check after each run... She has just been serviced and MOT'd and has a clean bill of health, she has always eaten oil... just a fact of driving in the power band everywhere, I rarely drive her in stealth mode, you know when I am close..... So, not one idea then from anyone ☹️ Well I shal have to keep searching...... Weirdy Its not the winning thats important, its the taking them apart.......

Myles Posted February 8, 2005 Share Posted February 8, 2005 V7's VHPD-based SLR drank oil. Project Scope-Creep is underway... Alcester Racing 7's Equipe - 🙆🏻™ Alcester-Racing-Sevens.com Link to comment Share on other sites More sharing options...
k80rum Posted February 8, 2005 Share Posted February 8, 2005 how weird... 😳 mine doesn't tend to use much oil at all.... and it's wet-sumped which you would think might make it more prone to wearing internal metal bits out. Mind you, mines only done 13k miles and I reckon i probably drive it like a wuss, that'd explain it 😬 Darren E K80RUM Superlight R #54 Link to comment Share on other sites More sharing options...
Mark Piper Posted February 9, 2005 Share Posted February 9, 2005 I'd not use 0-50 - Hyperion always used Mobil 1 motorsport in SLR - 15/40 IIRC. And my car's oil consumption varied - as little as a litre every 2k miles to a litre in 1,000 miles around the Le Mans weekend in 2003. Weirdy, what's your oil pressure at idle when hot and is the car dry sumped? Link to comment Share on other sites More sharing options...
Mark Piper Posted February 9, 2005 Share Posted February 9, 2005 Sorry meant to say that you may have trouble finding oil of that viscosity - I have about a litre of the old Mobil 1 oil of that viscosity in my shed if it's any good to you.... Halfrauds' oil (which is, or was, Comma SynerG) is, from memory something like 5/50. Link to comment Share on other sites More sharing options...
Jason Plato Posted February 9, 2005 Share Posted February 9, 2005 Mobil 1 Motorsport is currently 15w/50 Halfords "silver" synth is not the same as Commer SynerG (different colour)and is 5w/40 Link to comment Share on other sites More sharing options...
Weirdy Posted February 9, 2005 Author Share Posted February 9, 2005 Mark she's wet sumped. When hot at Idle the pressure can go right down if the levels are low on 0-50w. Anyhting other than 0-50w and the pressure can drop right off. When I queried this with Caterham they said as long as it goes up when you accelarate its fine, but thinner oils make the gauge go up and down and doesn't give a clear indication of pressure after a long run, decent High gloop oil has been the solution, burns less, runs smoother and the gauges give consistant readings.... NB: Please note when I say I drive her hard, this is not a ridiculous statement, Minty when cruising is usualy on the edge of the power band at 5k, when hooning it 6k upto the limiter at 7750k. She works hard and I am not ashamed to admit she is happy when thrashed completely.... I have tried Mobile motor sport, not gloopy enough, 0-50w is what She likes and is what I shall be feeding her.... So I guess I am going back to Caterham for thier coma 0-50w motorsport oil....

Jason Plato Posted February 9, 2005 Share Posted February 9, 2005 The 0w rating relates to cold viscosity , the 50 to hot viscosity . If Mobil 1 15w 50 isnt thick enough then I'm sorry but i do think your engine is shagged out You might want to act upon your strapline 😬 Link to comment Share on other sites More sharing options...
V7 SLR Posted February 9, 2005 Share Posted February 9, 2005 Mine drank oil because it was knackered. Prior to that it never used a drop. Link to comment Share on other sites More sharing options...
Weirdy Posted February 9, 2005 Author Share Posted February 9, 2005 Chaps, I maybe over exagerate about the consumption, it seems like alot...I check her level after every run.... If the engine is knackered it has been so since I bought it @ 900 miles, its now 12k and rising..... I don't think it is knackered TBH, I think I just thrash her more than most, well thats what she was built for.... Please also remeber I have stuffed a few sumps too, that adds to the oil loss... She is happy on 0-50w does this make her bad? curious minds need to know..... 😬 Weirdy Its not the winning thats important, its the taking them apart.......

oilman Posted February 9, 2005 Share Posted February 9, 2005 0w-50 😳 Is this right? Do you mean 5w-50? 0w is the cold crank viscosity and is useable in -35degC 😳 This is really overkill for UK climate. 10w is -20 degC. The problem with wide viscosity oils is that they are far more prone to shearing because they need bucket loads of VI Improvers to make them work. If your going to use an sae 50 then 10w-50 or 15w-50 is a better oil as the viscosity is not as wide. The consideration is whether this viscosity is too thick for your engine and therefore you're wasting power and causing friction as the engine struggles to pump the oil around. The most shear stable 0w grade available is in fact 0w-30 all things being equal. Cheers Simon Link to comment Share on other sites More sharing options...
Weirdy Posted February 9, 2005 Author Share Posted February 9, 2005 oilman food for thought.... no dicernable noticable differance in power.... maybe its better to have 5-50w as you say.... I understand the numbers as reguards the gloopyness, but blimey..... I have learned something new...... Weirdy Its not the winning thats important, its the taking them apart.......

frankyknuckles Posted February 9, 2005 Share Posted February 9, 2005 Howard, you need to read this thread There is loads of good advice in it (particularly from Peter Carmicheal and oilman), and as I think people are already suggesting on this thread, you should seriously consider a different oil grade and not listen to the marketing from CC. www.R300.net Link to comment Share on other sites More sharing options...
frankyknuckles Posted February 9, 2005 Share Posted February 9, 2005 Also, you may have mis-understood the above post from oilman, I think he is saying that if you increase to a thicker viscosity, you might realise a drop in bhp (but this might be outweighed by the benefit you will get from engine protection). www.R300.net Link to comment Share on other sites More sharing options...
dino ferrana Posted February 9, 2005 Share Posted February 9, 2005 Worth bearing in mind that Oilman does have a vested commercial interest and doesn't sell Mobil, Comma etc. Yet another thread suggesting Caterham got Comma to develop some cr*p oil for their cars. The development of this oil along with other improvements has improved the reliability of R500 engines. Weirdy I would use the 5W50 as you know it works! There is a lot of suspiscion on the board that Caterham do everything to spite people . Caterham said to me at the time when they developed them they did it to remove the confusion of what oil should go in what. Link to comment Share on other sites More sharing options...
frankyknuckles Posted February 9, 2005 Share Posted February 9, 2005 dino, I don't give 2 hoots about who sells on BC and who does not, but you cannot ignore the advice on the thread I have mentioned. At the end of the day pleople will take their own actions on what to do, but regardless, it is worth pointing Howard (wierdy) at the thread for his general understanding. www.R300.net Link to comment Share on other sites More sharing options...
oilman Posted February 9, 2005 Share Posted February 9, 2005 Dino, Correction - Oilman does sell Mobil. You're correct, he doesn't sell Comma because he already has 6 brands of oil to sell! You've obviously not done your homework http://www.opieoils.co.uk/lubricants.htm Cheers Simon Link to comment Share on other sites More sharing options...
dino ferrana Posted February 9, 2005 Share Posted February 9, 2005 Of course it is a free choice for everyone. Oilman however does sell oil and only sells certain brands. I am sure some of the advice can be generally applied but he does have a vested interest to recommend particular oils. I would say that Mobil Motorsport 15W50 is not a great choice for a K-Series as it doesn't get very runny at low temps. This is particularly critical at this time of year when oil doesn't get very hot even on longer blats. Link to comment Share on other sites More sharing options...
oilman Posted February 9, 2005 Share Posted February 9, 2005 I think the same can be said of Caterham who only recommend one oil, couldn't it? K Series - 5w-40 or 10w-40 Cheers Simon Link to comment Share on other sites More sharing options...
