Afton, Infineum, Lubrizol, & RohMax. I doubt there is ANY motor oil you can buy that doesn't have additives from at least two of those companies in it. As Mr. Likis says, you are buying 3/4 of a base oil (probably sourced from ExxonMobil, Sunoco, or one of the few other refineries) 1/4 of additives (which are blended amounts mostly from the 4 companies mentioned at the first). Most oil "brands" are just blending/packaging facilities.
Mobil 1 will run just fine. It is a very good oil. No need for snake oils. Just do regular oil changes as suggested by your car manufacture and you are good to go. My cars have lasted over 400k with plain old oil. It just got regular oil changes. Any major oil manufacture that meets the certification for your car is good enough.
Royal Purple is good stuff. PAO base stocks, group II additive carrier (AFAIK), nice additive package, and a shot of their Synerlec sulfurized ester. It should be noted that Royal Purple's new API SN/ILSAC GF-5 line no longer carries those elevated ZDDP levels or the Synerlec additive due to the lower sulfated ash quantities mandated by GF-5 and the API. Now you have to get Royal Purple's HPS line to get the old school Synerlec containing motor oils.
Royal Purple filters are recommended to go 12,000 miles themselves using a "micro-glass" media which is basically identical to Donaldson's Synteq nanofiber wire backed glass media.
There's no point in changing a Royal Purple filter at 6,000 miles other than to add that extra quart of oil for a TBN boost. If that's the concern there's STILL no need to change a $15 filter at half of its design life, just extract a quart and replenish with a new quart.
the fact that the royal purple made it last for 12k miles up to 200,000 miles.....wow. royal purple has shown why they are better. they basically have a lucas type additive in it i believe.
@kief4diamonds No Lucas type additive in Royal Purple. Royal Purple is the real deal while Lucas is nothing special. From what I have gathered the magic to Royal Purple is their Synerlec additive, which is simply a sulfurized monoester added in small quantities. The sulfur component boosts the oil's anti-wear performance while the ester component draws it to the metals of the engine through an oxygen-oxygen polar attraction.
@LieKiller I like that you get technical....some of us actually know what your talking about and enjoy going a little more in depth. thanks. i will use nothing but until something better comes out......added a catch can and there filter. car should love it. change it ever 3000 on the dot or before like always...valvetrain is quiet as a mouse even after the cam, supercharger and drag racing.
I use Mobil 1 High Mileage + 1 Quart of Royal Purple for a 6,000 mile interval, changing out my Mann oil filters every 3,000 miles.
I use BG MOA to top up the engine with the new filter, but I also pre-fill the filter with a MMO, BG MOA, and RP mix.
In the summer I use 10w-40, in the "winter" I use 5w-30.
Took the head apart for a "minor" head gasket leak, and the engine looked like new with a 133,000 miles on the clock... I'll think I'll continue with my routine...
Why not? The sooner you use synthetic oil the sooner you will experience the benefits of superior cold weather startup performance and high temperature protection.
@GTVAlfaMan Because if you have been running conventional oil for over 5 years then switch to synthetic then your seals loose there alasticity and dont tighten back up and you will get mad leaks.
@EasternEb58 Only true if you switch to a synthetic oil with poor seal swell characteristics. Any straight group III or group IV (PAO) oil exhibit those tendencies. Synthetic oil's containing an ester or alkylated napthelene (high polarity) component will prevent seal "dehydration".
@GTVAlfaMan There's plenty of synthetic oils out there with low viscosity indices and thus poor cold start performance in regularly seen cold start temps (0-100 degrees F).
ha amsoil sucks ass iv never had good luck with it in my small engines. stopped using it after my R1 blew up. I switched to klotz and flog the shit out of it daily after new factory engine and no problems. I do use RP for my cars and no problems. I had to replace the piston and rings every year when i was younger in my cr250 using amsoil very bad piston scuffing. i switched to klots bean-oil and only changed it 1 time in two years
I tried Royal Purple, It worked Very well the 1st month. Got up to 23MPG on a 2009 F-150, A month later It Dropped to 18-19. I use Mobile 1, but looking to try Amsoil.
AMSOIL API rated 25,000 miles or once a year since 1972 pretty much says it all.
If you can't extend your drain interval with a synthetic oil its because it not a true Synthetic group IV PAO its a Group III Hydrocracked refined oil
Amsoil makes nano oil filters that are rated for 15,000-25,000 miles depending on vehicle Oils rated for 15,000-25,000 miles also
Amsoil PAO Synthetics are called: The First in Synthetics" for a reason. That trade mark was allowed by the US Patent & Trade Office That includes Mobil 1 and Royal Purple The best base stocks and the best additives as Bobby Likis commented makes the best oil
Amsoil Full Flow and By Pass Filters keep the oil clean. Clean oil last longer
@Terry50031 Amsoil's claim as "The First in Synthetics" was handed to them on a silver platter by Hatco, who formulated and produced Amsoil's motor oils for their first 10 years or so. Amsoil's first offering was a Hatco produced diester oil. Amsoil now uses PAO, a cheaper alternative. Red Line uses the best base stocks out there (i.e. polyol ester) and has one of the most robust anti-wear/anti-friction additive packages on the market.
I run synthetic oil no longer than 6,000 miles with a Royal Purple oil filter, but thats just me and my engine has 92,000 miles on it and runs great as the first day it was used. I have used Pennzoil Ultra, Amsoil and Valvoline Synpower to date. I did run the Amsoil for 10,000 miles and had the oil tested afterwards and it still had 60% of it's additive package left in it. Amsoil is awesome.
AMSOIL is the BEST FULL synthetic Oil IN THE WORLD. That has been proven test after test after test. Mobile 1 and R.P. are NOT full synthetic oils, they are blends. AMSOIL was created in 1972, Mobile 1 in 1974, R.P. in ? There is no exact date listed any where for them. AMSOIL is 100% american made, Mobile 1 & R.P. use base oil from over seas. I have seen AMSOIL go 27,000 in a pickup truck, it was tested by an outside company and the oil was still good for another 5,000 miles.
The motor oil debate is overrated. If you just follow your owner's service manual, and use a good quality synthetic of the specified weight and (preferably) an OEM filter, the engine will probably end up burying you. It's true, you do get what you pay for, BUT the shelves at Pep Boys and Autozone are full of automotive snake oil, including all this injector cleaner crap and "Make your car run like rocket" in a bottle crap. Just do your maintenance, and you will be fine. RP is a rip off.
Amsoil was the first and still the best. Royal Purple is a good product but why follow a follower? They were the originator of the extended drain interval. No wonder this caller was concerned about the cost. He was changing the filter and the oil too often.
@tobroke2007 to be honest Royal Purple is not even API certified and still an SL oil. It's been known to be just for racing but they say it is street legal, but the API says it is not.
@funboy4u33 Just went to 3 stores today and all were SL. RP is trying to get rid of all the SL before they release the SN. PM me your email and I will forward an email I got from them. Take care....
this guy is a royal purple fan boy....and says that it isnt available in mass markets. Has he looked at a wal mart shelf in the last 2 years? Guess what...Royal Purple is there...and for $7 a quart. Amsoil out beats everyone even royal purple....
