Paul Wiley Posted August 26, 2004 Share Posted August 26, 2004 Redline Silkolene etc are open about base stock, it is more confusing in mid range as to what is the base stock, especially as companies reposition their product range. Paul Link to comment Share on other sites More sharing options...
david nelson Posted August 26, 2004 Share Posted August 26, 2004 I hope this helps Valvoline SynPower motor oil 001/10 Valvoline SynPower motor oil is a premium fully synthetic motor oil, formulated with the highest quality synthetic base oils, enhanced with the most advanced additive technology. SynPower motor oil provides the ultimate performance in meeting the latest requirements for virtually all cars and light trucks (vans) including gasoline, diesel, and LPG engines. SynPower motor oils provide superior protection at start-up, even under extreme conditions. Suitable for extra longdrain intervals (see approvals/performance levels). also found this here David Edited by - David Nelson on 26 Aug 2004 21:46:43 Edited by - David Nelson on 26 Aug 2004 21:47:54 Edited by - David Nelson on 26 Aug 2004 21:48:35 Link to comment Share on other sites More sharing options...
Paul Wiley Posted August 26, 2004 Share Posted August 26, 2004 Tony, I mentioned Jet engines a few posts back and perhaps with a car engine it may not be a good comparison! so the other side of coin Seal compatabilty of polyolester base stocks . http://www.ultracheminc.com/comp.htm Polyolesters are not interchangeable with PAO or mineral oils when it comes to seal materials. There's no magic chemistry available that's not available to everyone else. While polyolesters (and diesters) stick to metal, adding a bit of them to a PAO accomplishes the same thing. As to esters (both polyolesters and diesters) may have a problem with water, crankcase condensation, race or road use. Synthetics experienced a variety of problems with both seals and water in pioneering stage. Amsoil changed from a diester to a PAO! Mobil 1, a manufacturer of both PAOs and polyolesters, uses the polyolesters in jet and turbine lubricants, and uses PAO for automobiles! Link to comment Share on other sites More sharing options...
Peter MarieEa Posted August 26, 2004 Share Posted August 26, 2004 David That oil comparison is ofcourse an Amsoil advert' comparing a very small selection of American made oils. It is interesting that Redline, a very direct competitor of Amsoil was absent from the test, but I'm not surprised. Amsoil claimed a best by far HT/HS viscosity of 3.51. Redline's HT/HS viscosity is 3.8 for both their 5W-30 and 10W-30 oils which is even higher than Mobil 1's popular 0w-40. Quick7 Link to comment Share on other sites More sharing options...
YellowSeven Posted August 27, 2004 Share Posted August 27, 2004 Gents, A quick recommendation if you could, after reading this thread with interest I intend to try the Silkolene Pro S. I comes in two grades, 5w-40 & 10w-50 can someone tell me which would be best suited to a 1.6KSS that will be used only on the track? Thanks Link to comment Share on other sites More sharing options...
Peter Carmichael Posted August 27, 2004 Share Posted August 27, 2004 I would choose 5W40. SAE 40 is the recommended grade for the K-series and it has a decent VI. Link to comment Share on other sites More sharing options...
oilman Posted August 27, 2004 Share Posted August 27, 2004 I agree, go for the 5w-40 grade. Give me a call for prices when you are ready to do an oil change. Cheers. Simon. Link to comment Share on other sites More sharing options...
Peter MarieEa Posted August 27, 2004 Share Posted August 27, 2004 Simon, welcome back. Do you know what the HT/HS Viscosity of Silkolene's PRO-S 5W-40 and 10W-50 oils are; it's not shown on their Technical Data summaries? Thanks' Peter Quick7 Link to comment Share on other sites More sharing options...
oilman Posted August 31, 2004 Share Posted August 31, 2004 Wow! You guys have been busy whilst I was away sunning myself! Give me some time to pick up where I left off and hopefully I'll be able to continue assisting where required. (Sorry but I've 30 odd Clubs to catch up on!) Just a thought.......... Do you think the Club would mind us posting our prices on the products that we sell here? Along with advice of the best ones to use of course. How about a seperate thread dedicated to oil advice and recommendations admins? If anyone wishes to save me time catching up then please feel free to post your questions if you have any.

frankyknuckles Posted August 31, 2004 Share Posted August 31, 2004 I would choose 5W40. SAE 40 is the recommended grade for the K-series and it has a decent VI. Would this also be true for a dry sumped R300? (I would ask why this is different from the Caterham Comma oil, but I feel I would be given a sound verbal thrashing for not understanding all of this thread, which I have read most of 😳 ) Would it be a proper fully synthetic oil I need? Oilman, please feel free to email me with recommendations and prices for a K-series 1.8 Dry Sumped car. frankyknuckles@r300.net www.R300.net Edited by - frankyknuckles on 31 Aug 2004 21:25:22 Link to comment Share on other sites More sharing options...

Peter Carmichael Posted September 1, 2004 Share Posted September 1, 2004 Franky, A dry sumped car manages its oil temps better than the wet sumps. It gives its oil less of a hard time, temperature-wise, which makes the SAE 40 recommendation even more sensible. Link to comment Share on other sites More sharing options...
oilman Posted September 1, 2004 Share Posted September 1, 2004 HT/HS Viscosity tests. Firstly, beware comparing numbers as there are different tests at different temperatures and some are quoted in degF rather than degC which always looks more impressive so make sure you are comparing like for like. As regards to the ester based Silkolene PRO S and PRO R products here are the numbers based on the latest test which is - ASTM D4683 (Test Temperature 150 degC) Silkolene PRO S 5w-40 = 4.07cp Silkolene PRO S 10w-50 = 5.11cp Silkolene PRO R 15w-50 = 5.23cp A typically expected level would be between 2.9 and 3.2 for the above viscosities.

Petrolhead Posted September 1, 2004 Share Posted September 1, 2004 A typically expected level would be between 2.9 and 3.2 for the above viscosities So Silkolene is out then????

oilman Posted September 1, 2004 Share Posted September 1, 2004 To be honest, like for like the Silkolene stats are impressive, we wouldn't recommend it otherwise. All their products (even non ester) ones always stack up well as they use decent basestocks and additive packages. They are quality products as I've stressed before. I'm waiting for the Club Committee to come back to me concerning joining our "Clubs Oil Scheme" so that we can make things here official.

Paul Wiley Posted September 1, 2004 Share Posted September 1, 2004 Oilman Why is % ester so difficult to obtain? To recap Once you put an ester based synthetic type of product in you never start metal to metal, even after a year there should be a one, one millionth inch of film. Even if the car has been in storage. This is completely untrue of petroleum oil regardless of who makes it. Petroleum will come off just from it's own weight in time. Using this aprrox overview, which is to divide the kinematic viscosity at 100C by the HT/HS rate. LOWER is better for shear stability: Example: AMSOIL XL-7500 5w-30. Method: kinematic viscosity (10.3) divided by HT/HS rate (3.1), equals the ratio (3.32). Pro 5W-40:3.65 Pro 10w-50 3.54 Pro 15W-50:3.48 However from the following info Redline a known ester and M1? have a good low ratio Amsoil ASL (non-API) 5w-30: 3.31 Amsoil XL-7500 (API cert) 5w-30: 3.32 Castrol Syntec 5w-30: 3.32 Castrol GTX 5w-30: 3.45 Castrol Syntec Blend 5w-30: 3.48 Mobil 1 SuperSyn 5w-30: 3.24 Kendal GT-1 Syn 5w-30: 3.25 Redline Synthetic 5w-30: 2.86 Amsoil ASL (non-API) 10w-30: 3.39 Amsoil XL-7500 (API cert) 10w-30: 3.18 Castrol Syntec 10w-30: 3.22 Castrol GTX 10w-30: 3.45 Castrol Syntec Blend 10w-30: 3.48 Mobil 1 SuperSyn 10w-30: 3.15 Kendal GT-1 Syn 10w-30: 3.28 Redline Synthetic 5w-30: 2.81 Link to comment Share on other sites More sharing options...
