When To Go To Synthetic?

I'm wondering what the opinions are as far as how long to wait on a new vehicle before switching to a Synthetic Oil? I guess some vehicles ship with synthetic oil so maybe the idea of using Dino oil for break-in is just an old wive's tale??

On new vehicles you can switch to synthetic whenever you want. I usually switch at my first oil change (1000 miles for me).

What are the advantages to switching to synthetic oil? Fewer oil changes? Can run at higher temps? I tow a trailer. Would a syn oil be better then dino oil?

 

Thanks.

This is what I would do...

 

Syn. oil is better then dio oil..hands down...but it has to be from Mobil or Val.

 

At 1000 miles I would change to Mobil 1 or Val 10w-30 or 5w30....I would leave that in for about 3,000 to 5,000 miles.

 

After that I would change to AMSOIL 5w-30. You don't have to to change your oil for the next 30,000 miles or full year.

 

Trust me...It works and its the best stuff on earth.

 

Just do a google search on AMSOIL. The results speak for its self. Make sure you use a AMSOIL oil filter too.

 

FYI...if you were to use AMSOIL fuilds from head to tail you will be adding life to your truck...esp if you tow.

I will not be doing the 30,000 thing with Amsoil. and its not that simple. The filter has to be changed at certain intervals. A lot of people run a bypass filter. You MUST send oil samples to Blackstone to see how the oil is holding up along the way. Not for me. And I do use synthetic, 0W30 German Castrol, a true synthetic.

 

Anyway did you know that amsoil gets most of their Pao basestocks from Exonmobil. interesting.

 

Have a good one,

I used to hear wait 10-15,000 miles, but on a modern engine it really shouldn't matter at all.

 

Don't Corvettes come with Mobil 1 as the factory fill anyway?

Synthetics generally allow you to go for more miles between changes. I wouldn't stretch the mileage out too far without having an oil analysis done though. They run about $20. Synthetics provide better protection for the engine and keep it cleaner as well.

 

Synthetic doesn't cost much more than dino. You may as well use it. In a truck that tows, it is definitely a plus to have synthetic.

I'm a big fan of synthetics and currently use Amsoil. However, I would never run 30K between changes. I use a lab for oil analysis and although it lasts longer than the Mobil 1 I used in my Tahoe, I only get up to around 12K before it starts to breakdown. This using an Amsoil filter. I change it at 10K for insurance as I generally keep my vehicles for about 6 years and 200K.

 

As for the first change, I changed mine at 1000 miles

1000 mile mark in my Sierra. Done the same with my other vehicles without any problems.

I have run all my vehicles on Mobil 1 since 2001...Corvette and GTO come from the factory that way and I have had an Avalanche and Mazda 6 also outfitted this way...currently run the 2000 Escalade too...the trucks were treated to more severe weather conditions and the GTO and 'Vette to more severe, er, driving conditions...the Mazda 6...force of habit???...:jester:

You can change any modern vehicle immediately to synthetic...

If you use ethanol ,never use synthetic!!! it creates a kind of grease that may clogs the oil pump!!!

I burned one engine out (ford ranger 4.0 V6) using synthetic waiting for the 30.000 mile oil change ,it achieved only 13.000 miles and my engined burned out.

For me ,I would never use synthetic again ,I prefer to change the mineral at every 50% of oil life at the OLS.

I use Mobil1 full synthetic on all my vehicles, including gear lube, transmissision fluid, and frontend grease.

 

94' Z28 5.7L LT1 - 1st synthetic oil change at 2000 miles

04' Yukon 5.3L - 1st synthetic oil change at 1500 miles

08' Avalanche 5.3L - 1st synthetic oil change at 1300 miles

 

All with no problems. Also, a tip I always do before I put on the oil filter..

Fill it up with fresh oil along with a little oil on the gasket. It will take less time for

the oil pressure to build up during that initial startup. Any dry start is not good

for the engine.

      2 speed transfer case optional now?

      By newdude · Posted

      This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.

      Different requirements for oil filters?

      By newdude · Posted

      2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.

      Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉

      2020 Trailboss 6.2 replacement

      By newdude · Posted

      Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
