5 W 30, revisited
I Googled this here and found lots of conflicting data, so let me tell
the story: I got my 60,000 mile checkup done on my '99TJ 3 months ago at a dealer, with oil change included. Yesterday I went to change the oil and my drain plug had been crushed and totally stripped (the head, not the threads) apparently by an air wrench.So I took it back today and the dealer replaced the plug, and in so doing also changed the oil. My question: they used 5W30. I usually use Syntec 10W30. I noticed the sticker and asked the guy, and he said they use 5W30 all the time in TJs. (Apparently they use air wrenches to change oil, too, so I don't trust their judgment) They're a Jeep dealer, mind you. I live in Virginia and it gets hotter than hell in the summer. Is this safe? Isn't 5W30 too thin? Or am I worrying about nothing? If it is too thin, is there an additive I can toss in instead of another changeout for the next 3,000? Thanks in advance. Matt |
Re: 5 W 30, revisited
I used to believe 5W-30 was too thin but now look at it this way... the 5W
part means it's thin enough to quickly flow into the nooks and crannies of an engine when it's still cold. Quicker protection. When it's warmed up, 5W-30 is the same 30 weight viscosity that a 10W-30 is. I got point-of-view this from a Mobil-1 rep who understood I had concerns about 5W-30. I haven't switched from 10W-30 to 5W-30 yet but would have no reservations against doing so after having it explained to me as he did.

Re: 5 W 30, revisited
Don't run 5w-30 in high temps. See the chart in your owners manual.

Re: 5 W 30, revisited
That's an old wive's tale 5W-30 is 30 weight when warmed up just like 10W-30
is.
