Engine oil

[Midniteoyl]

I agree, VERY few vehicles ship with synthetic oil. Maybe 1 in a 1000 if that. And I doubt mfg's would ship ANYTHING w/o the proper protection... They must feel Dino protects just fine... After all they are on the hook for the first 100k

I do believe he was being sarcastic, Thomabear..

Don't think he understood what I was saying in my post. Glad you could spell it out for him

I understood exactly what you were saying.
What I do not understand is that you synthetic guys seem to think your vehicles will last xxxx miles longer if you throw unnecessary dollars at them. I guarantee this ain't so... It basically reminds me of the kind of mentality that if you put 200 year bricks on a 100 year house the whole house will last 200 years. How dumb is that? In my life of 54 years I have NEVER had a vehicle outlast an engine. Had I wasted my money on synthetic oil during their use it would have been just that.... Wasted money.... In fact the famous 1 million mile Dodge and 750K 7.3 power stroke ran nothing but conventional oil. Hmmm, how is that? This has to be impossible, right?
FWIW, I'm not gullible enough to believe synthetic oil is needed to carry my vehicles through their useful life and I certainly don't believe in paying an unnecessary premium for a warm fuzzy feeling.

Actually it's quite simple.... You believe and do what you will and I'll do the same. Oil debates aren't worth the argument IMO. See ya at 300K.

That's why he got a sarcastic reply.. :thumbsup:

This is an example for why VW/Audi recommends synthetic oils in their specs.. I.8 T Oil Pressure Light - Audi Forums

Try 188k on an '06 Sierra 4.8L...

Still going strong at 225k running Mobil 1 5W30 syn

How about 360,000 miles on 1970 Buick GS350 - castrol GTX 10-40 DINO only major engine work was new steel rocker shaft assemblies at 160,000 then again it is a Buick and it was running fine until the kid that bought it wrapped it around a phone pole...

I run Rotella in my Cummins equipped Dodge, but there is one thing I have noticed with the Rotella and that is an unmistakable smell of the engine oil (in the cab) for the first 1500 miles. I like the oil but not the aromatic nature of it... I guess it's a quirk of this vintage Dodge ...and Rotella

In my 187K mile Audi, the Mobil 5w-40 I was using disappeared faster than the Mobil 10w-40 High Mileage stuff.. So I used that in summer, and the 5w in winter.

That makes sense - thicker base in the 10W, less VII, and the HM will have added seal swellers/conditioners.

If one researches the volatility data, my point about lower synthetic consumption (same engine, same viscosity) should make sense. It's a nuance some people don't care about, but given the amount of seized motors I've seen at my buddy's shop, I thought I'd mention it.

Meaning - many people (not on here) need to get a clue, and check their oil - not that synthetic will cure male pattern baldness, cancer, and create peace in the Middle East :laughing:

As per my other post, I'm fine with conventional in certain applications. With my usage, there are differences in performance that matter to me under certain conditions.

The advantages to synthetic are many.

The biggest is the ability to run much longer oil change intervals.

That's one advantage.. However, VERY few people take advantage of extended OCI's. What's the other advantages other than extreme cold temp flow and high temps well above than what Dino will protect at? Any lab that performs UOA's will confirm that wear rates are the same. Blackstones website for example.
