&gt; Might that be from too thin oil?=C2=A0 As a long time cross-discipline=
 control system professional,=C2=A0 the lubricants=C2=A0 or use of improper=
 spec lubricants may be a cause, but not entirely, as when you tear into th=
ese new tech engines, they are yes, mechanical marvels controlled by comple=
x computer management, but also, mechanical nightmares more likely to self-=
destruct if a microparticle of contaminate invades the wrong internal spot,=
 a sensor allows the wrong stuff to enter the engine somewhere or the coola=
nt level drops because some plastic coolant manifold or connection has a we=
ak spot and suddenly dumped all the coolant creating a high temp spike on t=
he close tolerance components.<br>
&gt; <br>
&gt; We love the new tech performance, but at what cost?<br>
&gt; <br>
&gt; People slammed the Triumph Stag 2997 CC OHC V8 for its design &quot;fl=
aws&quot; but when I dive into some of these newer engines there are striki=
ngly similar designs copied, I have seen across many other engine manufactu=
rers including GM, Mercedes, Toyota, Ford, JLR and others.=C2=A0 One exampl=
e is timing chains, OHC design, etc.=C2=A0 Today&#39;s OHC engines, all of =
them, have issues with timing chain tensioners, guides, oil pumps which are=
 manifested from engine designs over 75 years ago but cost cut even more an=
d designed to very narrow performance limits and very close tolerance requi=
rements.<br>
&gt; <br>
&gt; When I look at these newer high-performance engines, they all appear t=
o have the same old issues: multiple simplex roller timing chains (some use=
 internal rubber belts!!!)=C2=A0 held in place by insufficiently designed g=
uides and tensioners driving all sorts of internal components like oil/fuel=
/water pumps buried deep internally into the engine, variable valve timing,=
 variable stroke, very high-pressure requirements for oil and fuel with ele=
ctronics like solenoids and sensors operating in the component lubricants, =
and they all have significant design structural problems from material and =
cost scrimping and lack of real longevity whether they are petrol/gas or di=
esel.<br>
&gt; <br>
&gt; I have been looking at the various JLR newer models, and what incredib=
le value can be had in say a Range Rover autobiography /SV/Dynamic/ that ha=
d cost 180k USD or far more, yet with a blown 5.0 liter engine, they are re=
latively worthless.=C2=A0 To rebuild one of those 3.0 or 5.0 engines, have =
a look at some of the teardown and rebuilds of any modern direct injection =
engine and you will quickly see the engines are all completely disposable d=
esigns; materials are skimped in the blocks to save manufacturing time, wei=
ght and maximize cooling, but when they break, they self-destruct. Labor al=
one to tear down and reassemble is often more that the OEM cost of the enti=
re engine, and the factory does not provide rebuild kits.=C2=A0 What is a p=
ound of engine webbing structural aluminum removed from a 600 bhp superchar=
ged engine as an assembly or weight saving design on a 6000# weight vehicle=
?=C2=A0 Maybe if designed for the track that amounts to a fraction of a sec=
ond of speed, but a road vehicle?!?<br>
&gt; <br>
&gt; Lubricants:<br>
&gt; Historically, the fact was, API / SAE lubricants designed for componen=
ts were once supposed to increase the range of mechanical protections with =
new specifications as time went on, where today, a mechanical component may=
 be designed only for one very narrow type of lubricant that was designed o=
nly for that unique application.<br>
&gt; <br>
&gt; The API/ SAE &quot;meets or exceeds&quot; statements must be carefully=
 dissected to understand exactly what the lubricant use range and component=
s lubricants are approved, which may take significant research.<br>
&gt; <br>
&gt; If you decide to use your &quot;favorite brand&quot; oil or coolant in=
 a modern driveline component not certified for use in that narrow design, =
you might be unknowingly starting the self-destruction timer.<br>
&gt; <br>
&gt; So, to answer the question for our old and very reliable vehicles, BEG=
IN with the Owner&#39;s Manual / Factory Manual specification for your lubr=
icants in and on your components as they were designed by the manufacturer,=
 and if that type of lubricant is not available, look and understand what a=
nd why it was replaced with a later API/SAE tested lubricant that &quot;sho=
uld&quot; add increased protection in that application.<br>
&gt; AVOID AT ALL COSTS, &quot;my buddies or I uses this and swears by it..=
.&quot;=C2=A0 I typically do not trust my local parts shoppe counter person=
 for lubricant recommendation unless that counter person was once a master =
mechanic or factory trained tech, that being rare.=C2=A0 There are reams of=
 Technical Service Bulletins where the factory engineers got it wrong too, =
only discovered during or after warranty periods.<br>
&gt; Lubrication is its own science, but if you read the specs, you will ge=
t the limitations and also the mechanics tales for snake oil.<br>
&gt; <br>
&gt; Caveat Emptor ya&#39;ll.<br>
