OK, thanks!Nope, we have three different engines in the FL's, from oldest to newest:
- C7 CAT
- Mercedes ~7L
- Cummins ISL
The ISL is actually the one that has the biggest difficulty starting in cold weather, even when it has been plugged-in all night.
The Kenworth has the Paccar (Cummins) PX-9.
Cold starting temps?Interestingly, the county here runs Delvac 1 5w-40 (or did) in the plow and salt trucks. Our local International dealer used to stock tons of it because that's where they bought it from. I haven't been in that shop since my buddy left for a foreman position managing a bus fleet, but I suspect that's still the case.
What is the advantage of EP then?Identical story except with Castrol and not for 35 years, but more like 6. I'll pay a few dollars to stick with what I know works, and if I get a rebate even better. I'd go M1 first before ST if I had to. Nothing wrong with ST, but I just don't want it for my applications. That said, I have tried other oils on and off, but my primary fill has been Castrol for a long time now.
I even pay the extra few bucks for EP but don't run extended intervals.
Cold starting temps?
OK, thanks!
I noticed on one of your other thread responses that you stated one was using synthetic 5w-40 and the other 15w-40. That could make a difference in one being easier to start. But you already know that!
I know nothing abut the Mercedes engine but from experience the CAT will use more fuel but will be more reliable than the Cummins.
I'm willing to pay 4 dollars for what might be a more stout oil. It's a feel good thing. I also have a strange application with a 1.4 turbo, tuned engine. Fuel dilution is a problem for me, along with high output on a hamster wheel sized engine.What is the advantage of EP then?
I am so going to miss the discussions of why people should pay twice as much for fancy oils when SuperTech works superbly. I love the guys who talk themselves into shelling out more dough than they need to.Not trying to start a forum war, but I've been wondering, if you're someone who changes oil frequently, does it make sense to use anything other than SuperTech synthetic? I've never used it before, what I've used previously is Mobil1 AFE, Valvoline SynPower, or Castrol Edge Titanium. My goal is to maximize engine reliability.
Is there really any difference using something like Castrol Edge vs SuperTech (both 5w30)? If both are D1G2, SN+, and GF-6 certified, and you do changes every 4,000 miles or so, what's the downside? I don't mind paying more if I'm getting my money's worth, but lately everything has been around double SuperTech's price. So if there's truly no benefit, I'd rather not throw away money.
Engine is an FA20DIT in a WRX. I take LSPI very seriously and I also know TGDI engines like to shear oil hence the frequent
I would NEVER use it in a BMWI am so going to miss the discussions of why people should pay twice as much for fancy oils when SuperTech works superbly. I love the guys who talk themselves into shelling out more dough than they need to.
There 2 stroke oil is low budget. "Never again!!!"I do use SuperTech for everything. It works, even in marine applications. The Costco Signature oil I use? Comes from the same factory SuperTech does. And cheaper at Costco
Their overpayment for products is their reward. Even if they select a known branded oil that is above a Supertech.I don't think anything you said is inaccurate. Some people are too good to use Walmart-brand engine oil or are too good to set foot in a Walmart store to get that oil though....
