Thwwx Neutral Newbie March 6, 2007 Share March 6, 2007 I went with Blackstone Labs simply because they provide an easy to read report with a basic interpretation of the results. Wearcheck also show extremely elevated numbers for sulphur which is odd. Link to post Share on other sites More sharing options...
Spidercool 1st Gear March 6, 2007 Share March 6, 2007 Another term of this is SOAP sampling, commonly used in aviation industries. Please note that it is not the figures that matter. What ppls looking for is the CHANGES in those figures. You need to collect another oil sample for anaylsis again (say 3 months later) and to make comparison to these figures to see which areas of the "metals" are deteriorating or giving you alarm. Right now,this set of readings is meaningless. Link to post Share on other sites More sharing options...
Trex101 3rd Gear March 7, 2007 Share March 7, 2007 It is not meaningless, these figure can be use as a baseline. The figure can also be use to compare with other analysis with similar engine. Overall wear rate is pretty normal, except the shearing down from 13.8cSt to 12.8cSt, Oxidation 36, Nitration 16 & Sulfation 28 is very very low which show's the oil is not overheat or even stress(good cooling system). Si at 11 is very low which also indicate his air filter is tight and working fine. Pb at 0 also show's very good bearing protection(very mild driving). Sulfur at 15000 are a form of additives, nothing meaningfull about these figure though. Zn of 1184 does shows that is oil is pretty robust in anti-wear additives. TAN 3.31 look pretty high though for 7.5k usage as normally the oil acid fighting additives are depleted when TAN exceed 1/2 of the oil virgin TBN number(RP 10w40 virgin TBN are 10.4) So overall, pretty normal result. Can try something thinner next oil change, maybe a 30wt. Link to post Share on other sites More sharing options...

Genie47 1st Gear March 9, 2007 Share March 9, 2007 Now that I can say I can read it easier, looks OK. Nothing to be alarmed about. Your driving style must be really gentle. Go thinner. Link to post Share on other sites More sharing options...
Kklee 6th Gear March 9, 2007 Share March 9, 2007 TAN 3.31 look pretty high though for 7.5k usage as normally the oil acid fighting additives are depleted when TAN exceed 1/2 of the oil virgin TBN number(RP 10w40 virgin TBN are 10.4) IMHO, 30wt should be approached with a little caution as most 30wt would have lower TBN values. E.g. for Schaeffer 5w30 with TBN of 7.5, using the comparison above, TAN is 0.5x TBN = 3.75 If trying out 30wt, would suggest the oil change and UOA be done at 5k instead.

Trex101 3rd Gear March 9, 2007 Share March 9, 2007 True, the benefit of TAN test when compare to TBN is it's acid number (growth rate) is pretty consistent (provided same driving pattern & condition) among different brand oil. Unlike TBN which can shows wide disparity (TBN depletion rate) with different oil. ↡ Advertisement Link to post Share on other sites More sharing options...
